A yogi who through perfect meditation has merged his consciousness with the Creator perceives the cosmical essence as light; to him there is no difference between the light rays composing water and the light rays composing land. Free from matter-consciousness, free from the three dimensions of space and the fourth dimension of time, a master transfers his body of light with equal ease over the light rays of earth, water, fire, or air. Long concentration on the liberating spiritual eye has enabled the yogi to destroy all delusions concerning matter and its gravitational weight; thenceforth he sees the universe as an essentially undifferentiated mass of light.
- from Autobiography of a Yogi by Paramahansa Yogananda
