Lamp (BG and SB)
Bhagavad-gita As It Is
BG Chapters 1 - 6
BG 6.19, Translation and Purport:
As a lamp in a windless place does not waver, so the transcendentalist, whose mind is controlled, remains always steady in his meditation on the transcendent Self.
A truly Kṛṣṇa conscious person, always absorbed in transcendence, in constant undisturbed meditation on his worshipable Lord, is as steady as a lamp in a windless place.
