"Kaunteya pratijānīhi na me bhaktaḥ praṇaśyati (BG 9.31). If one simply begins devotional service, he is immediately protected by the Supreme Personality of Godhead. This is also confirmed in Bhagavad-gītā (18.66): ahaṁ tvāṁ sarva-pāpebhyo mokṣayiṣyāmi. Protection begins immediately. The Lord is so kind and merciful that He gives the devotee proper guidance and all protection, and thus the devotee very peacefully makes solid progress in Kṛṣṇa consciousness without outward disturbances. A serpent may be very angry and ready to bite, but the furious snake is helpless when faced by a blazing fire in the forest. Although an enemy of a devotee may be very strong, he is compared to an angry serpent before the fire of devotional service."
