Because of insatiable material desires, I was being carried away by the waves of material natures laws, and thus I was engaging in different activities, struggling for existence in various forms of life.
As long as a living entity wants to fulfill various types of material desire, he must continuously change from one body to accept another. Srila Visvanatha Cakravarti Thakura explains that as a small piece of grass falls in a river and is tossed about with different types of wood and tree branches, the living entity floats in the ocean of material existence and is dashed and tossed amidst material conditions. This is called the struggle for existence. One kind of fruitive activity causes the living being to take one form of body, and because of actions performed in that body, another body is created. One must therefore stop these material activities, and the chance to do so is given in the human form of life. Specifically, our energy to act should be engaged in the service of the Lord, for then materialistic activities will automatically stop. One must fulfill ones desires by surrendering unto the Supreme Lord, for He knows how to fulfill them. Even though one may have material desires, one should therefore engage in the devotional service of the Lord. That will purify ones struggle for existence.
A person who has broader intelligence, whether he be full of all material desire, without any material desire, or desiring liberation, must by all means worship the supreme whole, the Personality of Godhead. (Bhag. 2.3.10)
anukulyena krsnanu-
silanam bhaktir uttama
[Madhya 19.167]
One should render transcendental loving service to the Supreme Lord Krsna favorably and without desire for material profit or gain through fruitive activities or philosophical speculation. That is called pure devotional service. (Bhakti-rasamrta-sindhu 1.1.11)
