The Yoga Sutras of Patanjali
BOOK III

Rightly understood, therefore, the whole life of the personal man is for another, not for himself. He exists only to render his very life and all his experience for the building up of the spiritual man. Only through failure to see this, does he seek enjoyment for himself, seek to secure the feasts of life for himself; not understanding that he must live for the other, live sacrificially, offering both feasts and his very being on the altar; giving himself as a contribution for the building of the spiritual man. When he does understand this, and lives for the Higher Self, setting his heart and thought on the Higher Self, then his sacrifice bears divine fruit, the spiritual man is built up, consciousness awakes in him, and he comes fully into being as a divine and immortal individuality.

36. Thereupon are born the divine power of intuition, and the hearing, the touch, the vision, the taste and the power of smell of the spiritual man.

When, in virtue of the perpetual sacrifice of the personal man, daily and hourly giving his life for his divine brother the spiritual man, and through the radiance ever pouring down from the Higher Self, eternal in the Heavens, the spiritual man comes to birth,--there awake in him those powers whose physical counterparts we know in the personal man. The spiritual man begins to see, to hear, to touch, to taste. And, besides the senses of the spiritual man, there awakes his mind, that divine counterpart of the mind of the physical man, the power of direct and immediate knowledge, the power of spiritual intuition, of divination. This power, as we have seen, owes its virtue to the unity, the continuity, of consciousness, whereby whatever is known to any consciousness, is knowable by any other consciousness. Thus the consciousness of the spiritual man, who lives above our narrow barriers of separateness, is in intimate touch with the consciousness of the great Companions, and can draw on that vast reservoir for all real needs. Thus arises within the spiritual man that certain knowledge which is called intuition, divination, illumination.

37. These powers stand in contradistinction to the highest spiritual vision. In manifestation they are called magical powers.
