Starting at the top left panel there is a jar, called Tsebum, sitting upon a Lotus throne. Underneath is Durva grass as the fronds of the lotus stem and blue and green rock cliffs. Behind the Tsebum is the Mahamudra mists. Tsebum or "long-life vase", is a jar in which the "nectar of immortality" is kept. The Durva grass is also a symbol of long life: because grass is highly resilient, it is believed to be immortal. Therefore, it proclaims the end of samsara, the successive death and rebirth of all beings It usually takes a long time to overcome samsara, and a longer life span will allow greater progress in moving towards enlightenment within a given cycle. The lotus is an important Buddhist motif. Images of the Buddha and other important persons often are shown seated on a lotus throne. The growth of the lotus, with its roots in mud, growing through water, and emerging as a wonderful plant above the water's surface, is seen as an analogy of the soul’s path from the mud of materialism to the purity of enlightenment, which you need a long life to accomplish. The way to get there is through the Buddhist scriptures; enter the rock cliffs: rock/cliff formation represents the syllable "E" which appears in the opening stanza of early Buddhist scriptures, ("'thus,' I have heard"). The blue and green cliffs represent the unmoving nature of the mind when enlightenment has been attained. When we get to that point of enlightenment we understand the Mahamudra mists. Mahamudra: the union of compassion and wisdom -- the ultimate realization of one’s true nature. They are represented as the transformation of our vices into the 4 powers of regret, vow, reliance, and remedy, so the practitioner will realize purification and enlightenment. This is also the basic meaning of the "Heart Sutra."
The two upper doors have a Phoenix sitting on an Ashoka throne with a few camp flowers sprinkled among the durva grass. The Phoenix is a mythical bird that that transcends all great cultures. It is endowed with magical qualities of auspiciousness, longevity, peace and resurrection, it is at the top of the bird pecking order as to significance.
