These mandalas, concentric diagrams, have spiritual and ritual significance in both Buddhism and Hinduism. The term is of Hindu origin and appears in the Rig Veda as the name of the sections of the work, but is also used in other Indian religions, particularly Buddhism. In the Tibetan branch of Vajrayana Buddhism, mandalas have been developed into sandpainting. They are also a key part of anuttarayoga tantra meditation practices.

Hinduism and buddhism
Buddhism
Tibetan for mandala in Vajrayana Buddhism usually depicts a landscape of the "Buddha-land", or the enlightened vision of a Buddha, which inevitably represents the nature of experience and the intricacies of both the enlightened and confused mind, or "a microcosm representing various divine powers at work in the universe." Such mandalas consist of an outer circular mandala and an inner square (or sometimes circular) mandala with an ornately decorated mandala "palace" placed at the center. Any part of the inner mandala can be occupied by Buddhist glyphs and symbols, as well as by images of its associated deities, which "symbolise different stages in the process of the realisation of the truth."

Kvarne (1975: p. 164) in his extended discussion of sahaja, discusses the relationship of sadhana interiority and exteriority in relation to mandala thus:

"...external ritual and internal sadhana form an indistinguishable whole, and this unity finds its most pregnant expression in the form of the mandala, the sacred enclosure consisting of concentric squares and circles drawn on the ground and representing that adamant plane of being on which the aspirant to Buddha hood wishes to establish himself. The unfolding of the tantric ritual depends on the mandala; and where a material mandala is not employed, the adept proceeds to construct one mentally in the course of his meditation."

Mandalas are commonly used by tantric Buddhists as an aid to meditation. More specifically, a Buddhist mandala is envisaged as a "sacred space," a "Pure Buddha Realm," and also as an abode of fully realised beings or deities. While on the one hand, the mandala is regarded as a place separated and protected from the ever-changing and impure outer world of samsara, and is thus seen as a "Buddhafield" or a place of Nirvana and peace, the view of Vajrayana Buddhism sees the greatest protection from samsara being the power to see samsaric confusion as the "shadow" of purity (which then points towards it). By visualizing "pure lands," one learns to understand experience itself as pure, and as the abode of enlightenment. The protection that we need, in this view, is from our own minds, as much as from external sources of confusion. In many tantric mandalas, this aspect of separation and protection from the outer samsaric world is depicted by "the four outer circles: the purifying fire of wisdom, the vajra circle, the circle with the eight tombs, the lotus circle." The ring of vajras forms a connected fence-like arrangement running around the perimeter of the outer mandala circle.

The mandala is also "a support for the meditating person," something to be repeatedly contemplated to the point of saturation, such that the image of the mandala becomes fully internalised in even the minutest detail and can then be summoned and contemplated at will as a clear and vivid visualized image. With every mandala comes what Tucci calls "its associated liturgy...contained in texts known as tantras," instructing practitioners on how the mandala should be drawn, built and visualised, and indicating the mantras to be recited during its ritual use.

As a meditation on impermanence (a central teaching of Buddhism), after days or weeks of creating the intricate pattern of a sand mandala, the sand is brushed together and placed in a body of running water to spread the blessings of the mandala.

A mandala can also represent the entire universe, which is traditionally depicted with Mount Meru as the axis mundi in the center, surrounded by the continents. A "mandala offering" in Tibetan Buddhism is a symbolic offering of the entire universe. Every intricate detail of these mandalas is fixed in the tradition and has specific symbolic meanings, often on more than one level.

The mandala can be shown to represent in visual form the core essence of the Vajrayana teachings. In the mandala, the outer circle of fire usually symbolises wisdom. The ring of 8 charnel grounds represents the Buddhist exhortation to always be mindful of death, and the impermanence with which samsara is suffused: "such locations were utilized in order to confront and to realize the transient nature of life." Described elsewhere: "within a flaming rainbow nimbus and encircled by a black ring of dorjes, the major outer ring depicts the eight great charnel grounds, to emphasize the dangerous nature of human life." Inside these rings lie the walls of the mandala palace itself, specifically a place populated by deities and Buddhas.

One well-known type of mandala, in Japan is the mandala of the "Five Buddhas", archetypal Buddha forms embodying various aspects of enlightenment. Such Buddhas are depicted depending on the school of Buddhism, and even the specific purpose of the mandala. A common mandala of this type is that of the Five Wisdom Buddhas (a.k.a. Five Jinas), the Buddhas Vairocana, Aksobhya, Ratnasambhava, Amitabha and Amoghasiddhi. When paired with another mandala depicting the Five Wisdom Kings, this forms the Mandala of the Two Realms.



Hindisum
A yantra is a two- or three-dimensional geometric composition used in sadhanas, or meditative rituals. It is thought to be the abode of the deity. Each yantra is unique and calls the deity into the presence of the

practitioner through the elaborate symbolic geometric designs. According to one scholar, "Yantras function as revelatory symbols of cosmic truths and as instructional charts of the spiritual aspect of human experience"

Many situate yantras as central focus points for Hindu tantric practice.Yantras are not representations, but are lived, experiential, nondual realities. As Khanna describes:
Despite its cosmic meanings a yantra is a reality lived. Because of the relationship that exists in the Tantras between the outer world (the macrocosm) and man's inner world (the microcosm), every symbol in a yantra is ambivalently resonant in inner-outer synthesis, and is associated with the subtle body and aspects of human consciousness

Each syllable of the mantra represents a specific quality:

"Om" represents the pure exalted body, speech, and mind of enlightened beings.
"Mani" symbolizes the jewel, which stands for the altruistic intention to attain enlightenment.
"Padme" means lotus and represents wisdom.
"Hum" signifies indivisibility and unity.
When reciting or meditating upon this mantra, practitioners aim to cultivate compassion, wisdom, and a deep understanding of the interconnectedness of all beings. It is believed to have the power to purify negative emotions, liberate from suffering, and lead toward enlightenment.

The mantra is often chanted, written, or inscribed on prayer flags, wheels, and stones. Its resonance and repetition are said to create positive vibrations that benefit both the practitioner and the surrounding environment.

These sacred paintings serve as objects of contemplation, inspiration, and instruction, guiding practitioners on their spiritual path. Thangkas provide a visual gateway to the world of Tibetan Buddhism, encapsulating its rich symbolism, iconography, and spiritual concepts. With their vibrant colors, intricate patterns, and skillful craftsmanship, thangkas offer a profound visual medium for deepening one's understanding and connection to the teachings of Buddhism.

Thangkas come in various sizes, ranging from small pieces resembling Western half-length portraits to grand-scale creations spanning several meters in each dimension. While the larger thangkas are intended for temporary display during religious festivals, the majority of these artworks are designed for personal meditation or as educational aids for monastic students. The compositions of thangkas are meticulously crafted, featuring intricate details and often incorporating numerous small figures. A central deity or focal point is typically surrounded by a symmetrical arrangement of other divine beings, symbols, or narrative elements that convey profound spiritual teachings.

How is Thangka made

First, the canvas on which the painting is to be executed is laid on a wooden frame to determine the required dimensions. This canvas is an extremely finely woven cotton material, referred to in the Holy Scriptures as "Çura Canvas".

Then the canvas is cut, hemmed and, with the use of sturdy strings, very tightly mounted in the wooden frame. Painting is carried out with the frame in an upright position, without any further rigid support or backing.

In this studio, our primary artist, who works virtually exclusively for us, applies the undercoat consisting of a mixture of chalk and glue to the canvas by hand. Other Thangka workshops have turned to mainly using industrially pre-primed canvas.

This photo shows how the canvas, after receiving its base coat followed by a second coating of bone glue, is polished and smoothed by hand with a stone to attain a perfectly smooth, featureless painting surface. Through this process the canvas becomes quite rigid, thereby providing perfect conditions to evoke very finest artistic detail and over-all superior painting quality.

Using a different Thangka, we see how, after mounting, the complete basic pattern of the respective theme is applied to the canvas.

The following picture shows the steps in creating a gold-based Thangka, such as our No PH 9, the "Holy Mount Kailash". To achieve more intensive colour, yet another prime coat, in ochre, is applied, followed by a coat of pure gold. The so-called Thangka painting gold is traditionally produced by members of the Newar people in Nepal. 24-karat gold is ground to finest powder and mixed with bone glue and water in proportions suitable for direct use in painting. Thus, the Thangka gold is not gold leaf at all! Silver can be processed and used in the same way: Mount Kailash and the surrounding peaks in our completed Thangka were not painted with white paint, rather with precious silver.

Here, the nearly completed piece has been removed from the wooden frame. Now only the very finest finishing touches remain to be added, such as compacting the gold and giving Mount Kailash its silver mantle.

K. Lama regarded his already half-finished thangka proudly

The Mount Kailash Thangka, including the black margin (which can also facilitate the fastening of a traditional brocade frame), is now complete. Only the background gold must be compacted in the places where it is later intended to exhibit a sheen.

Here we see an old ballpoint pen casing into which a specially cut agate has been fitted. The back of this semi-precious stone is slightly concave and can be used to compact gold over extensive areas of the Thangka, while the blunt point is used to lineally compact gold, thus creating a shiny effect.

In this way, through partial compaction of the gold or refraining from compaction, nearly three-dimensional effects can be achieved. The glorious sheen of gold artistically treated in this way richly rewards the beholder or meditator with a Thangka possessed of an extraordinarily aesthetic aura.
