“The Mundaka Upanishad confirms that the Supreme Lord, in whom everything is resting, can be realized only by those who engage constantly in thinking of Him. This constant thinking of Krishna is smaranam, one of the methods of devotional service. It is only by devotional service to Krishna that one can understand his position and get rid of this material body.” (Shrila Prabhupada, Bhagavad-gita, 10.12-13 Purport)
