yatha dipo nivata-stho
nengate sopama smrta
yunjato yogam atmanah
Meaning: 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 Krishna (divine) conscious person, always absorbed in transcendence, in constant undisturbed mediation on his worshipable lord, is as steady as a lamp in a windless place.
