"It is confirmed in the Bhagavad-gita that the purpose of Vedic knowledge is to find Krishna. And it is said in the Brahma-samhita that it is very difficult to find Krishna, the Supreme Personality of Godhead, by systematic reading of the Vedic literature. But He is very easily available through the mercy of a pure devotee. The pure devotees of Vrndavana are fortunate because they can see Mukunda (Lord Krishna) all the time. This word "mukunda" can be understood in two ways. Muk means liberation. Lord Krishna can give liberation and therefore transcendental bliss. The word also refers to His smiling face, which is just like the kunda flower. Mukha also means face. The kunda flower is very beautiful, and it appears to be smiling. Thus the comparison is made."
