I have been doing some diligent research on Self realization and one thing i have seen common in most of the spiritual practices is Devotion and Yoga (Meditation).
In this age of Kaliyug is Hare Krishna Mahamantra the most effective mantra ?
I read somewhere OM is the best mantra..
Second Question :
Is chanting just enough for the realization or we should do Yoga parallely like kriya Yoga..
