Inner devtas such as Vivasvan, Indra and Mitra spread over two bhoomis, Dev and Manushya, which is why that line is erased. Earlier the band was divided into boxes; today the angular method is used. Each 90 degree quarter holds 10 equal boxes of 9 degrees: the main devta covers 6 boxes (54 degrees) and each side devta 2 boxes (18 degrees). The 32 outer devtas and Brahma make 33, and the 12 inner devtas complete the 45.
With the zoning chakra, align centre to centre and north to north: its black lines give the 32 outer devtas and its yellow lines the inner devta boundaries, drawn only in the middle band. Marking all devtas takes five to seven minutes.
