Just as one cannot see full image of Sun or Moon in unstable and wavy water.
Just as one cannot see the complete beauty of the face of Urvashi the divine fairy in a dirty mirror.
Just as without the light of a lamp, one cannot even see a thing lying close by. A house in darkness looks scary and frightening beside fear of intrusion of thieves.
So is the mind entangled in the darkness of mammon (maya). An ignorant mind cannot enjoy the unique bliss of the contemplation of True Guru and meditation on Lord's name. (496)
