In the Bhagavad-gītā also the Lord says: “Give up all your occupations and just become surrendered unto Me. I give you assurance that I shall give you protection from all sinful reactions.” 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 Kṛṣṇa in the Bhagavad-gītā.

Purity of Devotional Service
All of the previous instructions imparted by Śrīla Rūpa Gosvāmī in his broad statements can be summarized thus: as long as one is materially inclined or desirous of merging into the spiritual effulgence, one cannot enter into the realm of pure devotional service. Next, Rūpa Gosvāmī states that devotional service is transcendental to all material considerations and that it is not limited to any particular country, class, society or circumstance. As stated in Śrīmad-Bhāgavatam, devotional service is transcendental and has no cause. Devotional service is executed without any hope for gain, and it cannot be checked by any material circumstances. It is open for all, without any distinction, and it is the constitutional occupation of the living entities.
