The Yoga Sutras of Patanjali
BOOK III

44. Mastery of the elements comes from perfectly concentrated Meditation on their five forms: the gross, the elemental, the subtle, the inherent, the purposive.

These five forms are analogous to those recognized by modern physics: solid, liquid, gaseous, radiant and ionic. When the piercing vision of the awakened spiritual man is directed to the forms of matter, from within, as it were, from behind the scenes, then perfect mastery over the 'beggarly elements' is attained. This is, perhaps, equivalent to the injunction: 'Inquire of the earth, the air, and the water, of the secrets they hold for you. The development of your inner senses will enable you to do this.'

45. Thereupon will come the manifestation of the atomic and other powers, which are the endowment of the body, together with its unassailable force.

The body in question is, of course, the etheric body of the spiritual man. He is said to possess eight powers: the atomic, the power of assimilating himself with the nature of the atom, which will, perhaps, involve the power to disintegrate material forms; the power of levitation; the power of limitless extension; the power of boundless reach, so that, as the commentator says, 'he can touch the moon with the tip of his finger'; the power to accomplish his will; the power of gravitation, the correlative of levitation; the power of command; the power of creative will. These are the endowments of the spiritual man. Further, the spiritual body is unassailable. Fire burns it not, water wets it not, the sword cleaves it not, dry winds parch it not. And, it is said, the spiritual man can impart something of this quality and temper to his bodily vesture.

46. Shapeliness, beauty, force, the temper of the diamond: these are the endowments of that body.

The spiritual man is shapely, beautiful strong, firm as the diamond. Therefore it is written: 'These things saith the Son of God, who hath his eyes like unto a flame of fire, and his feet are like fine brass: He that overcometh and keepeth my works unto the end, to him will I give power over the nations: and he shall rule them with a rod of iron; and I will give him the morning star.'

47. Mastery over the powers of perception and action comes through perfectly concentrated Meditation on their fivefold forms; namely, their power to grasp their distinctive nature, the element of self-consciousness in them, their inherence, and their purposiveness.
