Out of compassion for them I, who dwell within their heart, destroy the darkness born of ignorance by the shining lamp of knowledge.
Out of compassion I destroy the darkness of their ignorance. From within them I light the lamp of wisdom and dispel all darkness from their lives.
When meditation is mastered, the mind is unwavering like the flame of a lamp in a windless place.
As a lamp in a spot sheltered from the wind does not flicker, this simile is used for the subdued mind of a yogi practicing meditation on Brahman.
