Bhagavad-gita 2.70 Purport
Although the vast ocean is always filled with water, it is always, especially during the rainy season, being filled with much more water. But the ocean remains the same-steady; it is not agitated, nor does it cross beyond the limit of its brink. That is also true of a person fixed in Krsna consciousness. As long as one has the material body, the demands of the body for sense gratification will continue. The devotee, however, is not disturbed by such desires because of his fullness. A Krsna conscious man is not in need of anything because the Lord fulfills all his material necessities.
