There are two ways of passing from this world — one in light, and one in darkness. When one passes in light he does not come back but when one passes in darkness he returns.
Bhagwad Gita 8.26
When the force of the desire for Truth blossoms, selfish desires wither away, just like darkness vanishes before the radiance of the light of dawn.
Do not extinguish the lamp of Divine Grace and do not let the candle of wisdom die out in the darkness of lust and error.
Above the cloud with its shadow is the star with its light. Above all things reverence thyself.
Truly, it is in darkness that one finds the light, so when we are in sorrow, then this light is nearest of all to us.
