1 Gita Sloka  every day - Chapter 10 - Vibhuti Yoga - Sloka 11

Tesham eva anukampa artham aham agyana jam tamah I

Nashayami atma bhavastah gyana deepena bhasvata II sloka 11

तेषां एव अनुकम्पा अर्थम् अहं अज्ञान जम् तमः I
नाशयामि आत्म भावस्थः ज्ञान दीपेन भास्वता  II श्लोक 11

Out of pure compassion for them. dwelling in their hearts, I destroy the ignorance-born darkness, by the luminous lamp of wisdom.

The Lord's choosing to dwell in the hearts of  beings is his compassion. Because of his presence as conscience, beings are prompted to seek what is good or atleast what seems good. The lamp of wisdom that the lord lights is constituted of divine components. Discrimination functions as the container of oil. The contentment coming from bhakthi is the oil. The flame gets put out by foul air. But this flame is fed by the pure air of meditation on Iswara. Prajna or the awareness of the self ensuing from the constant brahmacharya serves as the wick. The heart freed from all worries and anxieties is the lamp. A burning lamp runs teh risk of getting blown out by a gust of wind. but a mind unaffected by attachment and aversion is the best windscreen for this lamp. The unbroken consciousness of Iswara is the flame emanating from this lamp of wisdom, set up in the heart of the devotee. He beholds the divine presence within himself with the aid of this divine lamp. 

A policeman patrolling at night carries a bull's-eye lantern with the aid of which he sees persons loitering about. But this lantern doesnot disclose its carrier. If he, however, turns it on himself, the others then come to know who he is. Likewise Iswara reveals nature and its contents, but keeps himself hidden. Nobody can see him except through his grace and compassion
