Swami Papa Ramdas
Purity is the bedrock of spirituality. If you are not free from the six evils of Kama, Krodha, Lobha, Moha, Mada and Matsarya, you will not get God vision.
To be free from these evils, the best method is to remember God constantly and chant His Name.
By such ceaseless remembrance, all the Vasanas of the mind which bind you to the world, causing misery, are gradually destroyed and the once restless mind is made calm. Then it is able to stay longer and longer in God with one-pointed devotion for Him.
