SB 10.47.30 — By Myself I create, sustain and withdraw Myself within Myself by the power of My personal energy, which comprises the material elements, the senses and the modes of nature.
SB 10.47.31 — Being composed of pure consciousness, or knowledge, the soul is distinct from everything material and is uninvolved in the entanglements of the modes of nature. We can perceive the soul through the three functions of material nature known as wakefulness, sleep and deep sleep.
SB 10.47.32 — As a person just arisen from sleep may continue to meditate on a dream even though it is illusory, so by the agency of the mind one meditates on the sense objects, which the senses can then obtain. Therefore one should become fully alert and bring the mind under control.
SB 10.47.33 — According to intelligent authorities, this is the ultimate conclusion of all the Vedas, as well as all practice of yoga, Sāṅkhya, renunciation, austerity, sense control and truthfulness, just as the sea is the ultimate destination of all rivers.
