"The sufferings of human society cannot be counteracted by material plans. The only way suffering can be mitigated is by Krishna consciousness. When one takes to Krishna consciousness and engages himself in the devotional service of the Lord -- beginning with chanting and hearing the glories of the Lord -- the cleansing of the heart begins. When the heart is actually cleansed, one can clearly see the Lord sitting there without any disturbance. In Srimad-Bhagavatam (9.4.68) the Lord confirms that He sits within the heart of the pure devotee: sadhavo hridayam mahyam sadhunam hridayam tv aham."
(Caitanya-caritamrita Madhya 12.135, Purport)
