28.72

As for 'reaching the skipped alternating marks accomplishment,' this explains the cultivation of skipping. When a meditator cultivates the skipping absorption, first, regarding the defiled samāpattis of the eight stages, one repeatedly practices them manifesting in direct and reverse order, uniformly and successively; next, regarding the undefiled samāpattis of the seven stages, one repeatedly practices them manifesting in direct and reverse order, uniformly and successively; next, regarding the defiled and undefiled samāpattis, one repeatedly practices them manifesting in direct and reverse order, alternatingly and successively; next, regarding the defiled, one repeatedly practices them manifesting in direct and reverse order, uniformly and skippingly; next, regarding the undefiled, one repeatedly practices them manifesting in direct and reverse order, uniformly and skippingly: this is called the completion of the preparatory cultivation of skipping. Afterward, regarding the defiled and undefiled samāpattis, manifesting in direct and reverse order, alternatingly and skippingly, is called the accomplishment of the skipping absorption.
