"Therefore, in the Tenth Chapter it is said, tesam satata-yuktanam bhajatam priti-purvakam. By some way or other, who has become engaged in devotional service twenty-four hours, satata -- satata means twenty-four hours -- satata-yuktanam, with faith -- 'Now I am engaged in Krishna's service. Krishna will be... Actually He'll be merciful upon me. He'll deliver me from this miserable condition of material life' -- tesam satata-yuktanam bhajatam priti-purvakam. So Krishna is within. You cannot deceive Krishna. That is not possible. Krishna is the Supreme. If you are deceiver, Krishna is also the supreme deceiver. And if you are lover, then Krishna is the supreme lover. Ye yatha mam prapadyante tams tathaiva bhajamy aham. You deal with Krishna. As you deal, He'll also... He reciprocates. That is Krishna."
