"The devotees express their minds before the Deity, and in many instances the Deity also gives answers. But one must be a very elevated devotee in order to be able to speak with the Supreme Lord. Sometimes the Lord informs the devotee through dreams. These exchanges of feelings between the Deity and the devotee are not understandable by atheists, but actually the devotee enjoys them."
