The sages say that when we surrender to the Lord, we will clearly see how the He personally makes arrangements for us, even in small matters. Then we will easily see how with His omnipotent supreme intelligence He is assisting us out of love. So it is unnecessary to waste time in further speculation. We have to vanquish illusion, develop equanimity and spontaneity, and practice bhakt-yoga. Then a supremely powerful force will gradually transform our material existence into spiritual existence. All our misconceptions, accumulated over millions of lifetimes, will be rectified in a short time. Hence we need not become anxious because of a lack of time. The eightfold yoga practice—yama, niyama, āsana, prāṇāyāma, and so on—gives quick results, and one feels that he is doing something substantial. However, although such efforts may certainly make one materially proficient, they are nevertheless simply human endeavors. They are totally distinct from the activities carried out by the Lord's potency. The Supreme Lord's energy often works in subtle ways, but where it ultimately takes us is inconceivable to the human mind.
The mundane processes for elevation are, after all, initiated by intelligent human brains. They are like man-made canals: useful for easy transportation from one place to another, but otherwise of limited utility. Human efforts are imperfect, and therefore they keep us in the material world.
