The Religion and Philosophy of the Veda and Upanishads v2.c30.s18.5

v2.c30.s18.5

Rules are given for building up the Dvādaçāha to longer Sattras; the simplest addition is that of a Mahāvrata day after the period of ten days: other additions are inserted before that period, the shorter before the longer. But these rules are very much varied in practice. Of the various forms by far the most interesting is the Gavām Ayana, ‘the way of the cows’, which is a Sattra of one year’s duration.
