CC Madhya 4.62
śaṅkha-gandhodake kaila snāna samādhāna
After the mahā-snāna was finished, the Deity was again massaged with scented oil and His body made glossy. Then the last bathing ceremony was performed with scented water kept within a conchshell.
In his commentary on this occasion, Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura quotes from the Hari-bhakti-vilāsa. Barley powder, wheat powder, vermilion powder, urad dhal powder and another powder preparation called āvāṭā (made by mixing banana powder and ground rice) are applied to the Deity’s body with a brush made from the hair at the end of a cow’s tail. This produces a nice finish. The oil smeared over the body of the Deity should be scented. To perform the mahā-snāna, at least two and a half mānas (about twenty-four gallons) of water are needed to pour over the body of the Deity.
