For example, we can understand that the ocean contains approximately so many quadrillion tons of water. We can approach the understanding of the ocean's volume in this way but we cannot really fit it into our head as easily as we can with a smaller quantity of water, say a small pond or even a lake. But by analyzing a single drop of ocean water, we can understand the qualities that are present in the ocean. It would be difficult to describe Gaudiya Vaishnavism without describing the basics of Brahman realization. It is part of my nature to seek aananda or bliss.
Special emphasis is given to congregational chanting, or sankiirtana.
This is not strictly true. Renunciation, devotion, and scholarship have always been emphasized in the Gaudiya line, as evidenced by titles like Bhaktivedanta. By practicing pure devotional service the heart becomes cleansed of impurities and one comes progressively to the ultimate goal of prema-bhakti, or ecstatic devotion. While Gaudiyas have never insisted that others accept the divinity of Sri Chaitanya, they have in the past staunchly defended the scriptural basis of this worship. These are considered extraneous impediments to cultivation of unalloyed bhakti.
