In all phases of life, one has to perform devotional activities under the direction of the spiritual master in order to attain perfection in Bhakti Yoga. It is not that one has to confine or narrow one's activities. Krishna is all pervading. Therefore, nothing is independent of Krishna, as Krishna himself states in Bhagavad Gita 09.04 — The Nectar of instruction, Text 03.
Lord can protect one from the most dangerous type of fear.
Krishna has his own inconceivable ways for bringing a living entity back to his lotus feet.
The Lord is not dependent on anyone’s mercy for His opulence; He is always self-sufficient.
Srimad Bhagavatam 3.16.21,
