To understand Krishna, Chant Hare Krishna
Unless one is advanced in krsna-prema, love of Krsna, he cannot see or understand. By the blunt material senses, we cannot even understand the name of Krsna. People are always asking, "Why are these people chanting Hare Krsna?" They cannot understand, although Krsna realization begins with the name. The name of Krsna and Krsna are nondifferent, but we cannot realize this intellectually. Krsna is within the heart, and the contaminations are also there, but Krsna will help us cleanse them. Haridasa Thakura was chanting three hundred thousand holy names a day, but we have fixed the number at sixteen rounds. Nonetheless, we are so unfortunate and fallen that we cannot even perform them.
We have to practice chanting Hare Krsna to realize it. When we actually advance in devotional service and chant the Hare Krsna maha-mantra offenselessly, we will realize that Krsna and His name are nondifferent.
