In tantric Buddhism we find the principle of vibration or sound expressed in the inner practices of transformation where we imagine and develop a mandala, or a pure vision of the dimension of a particular deity or enlightened being. It’s a facsimile of the dimension of a deity, a spontaneous effulgent radiance of reality, in order to transform our limited dualistic vision of reality into the total vision of enlightenment and realize the qualities of enlightened wisdom through that particular deity.
Shariputra, form is emptiness and the very emptiness is form; emptiness does not differ from form, form does not differ from emptiness; whatever is form, that is emptiness, whatever is emptiness, that is form, the same is true of feelings, perceptions, impulses and consciousness.
According to Tibetan medicine everything has its origin in the mind which is the creator of the internal and external phenomena and the five elements which constitute physical reality. According to Buddhism, the mind is like a pure crystal which is obscured by temporary ignorance of its own original primordially pure state and by the subsequent karmic formations.
