If all types of worship, worship of Lord Krishna is best and better than the worship of Lord Krishna is the worship of His devotee, the Vaisnava.
I am seated in everyone’s heart and from Me come remembrance, knowledge and forgetfulness. By all the Vedas, I am to be known. Indeed, I am the compiler of Vedanta and I am the knower of the Vedas.
