Hare Krishna !
Krishna Consciousness is Science . As per our Guru's it's the real , correct and only true path for a living being. How to realize this ? One point of view is to follow the path told by Scriptures and Guru and other is to listen your heart, your inner calling. There is no voice from my heart or inner calling which says me this is the path I must follow ! Or rather this may be correct path ,but I am not getting convinced about it!
P.S I chant 6-7 rounds daily for last 6 months
