Sri Krsna is like the sun, and the materialistic speculations about the Absolute Truth are like the darkest midnight. As soon as the Krsna sun is arisen within one's heart, the darkness of materialistic speculations about the Absolute Truth and the living beings is at once cleared off. In the presence of the sun, the darkness cannot stand, and the relative truths that were hidden within the dense darkness of ignorance become clearly manifested by the mercy of Krsna, who is residing in everyone's heart as the Supersoul.

We can get that Krishna sun rising within our heart by hearing submissively from the bona fide spiritual master.  Thus whenever we get the opportunity for such hearing we should take full advantage of it.
