"One may think that because he is surrendering unto the Supreme Personality of Godhead he will not be able to perform all of his other obligations. But the Lord says repeatedly, 'Don't hesitate. Don't consider that because you are giving up all other engagements there will be some flaw in your life. Don't think like that. I will give you all protection.' That is the assurance of Lord Krishna in Bhagavad-gita."
