Text 19

यथा दीपो निवातस्थो नेङ्गते सोपमा स्मृता ।
योगिनो यतचित्तस्य युञ्जतो योगमात्मनः ॥१९॥

yathā dīpo nivāta-stho
neńgate sopamā smṛtā
yogino yata-cittasya
yuñjato yogam ātmanaḥ

Translation:

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.

Purport:

A truly Krishna conscious person, always absorbed in transcendence, in constant undisturbed meditation on his worshipable Lord, is as steady as a lamp in a windless place.
