Interesting features are also the mention of two series of seven prakṛtis (1.31),⁴²¹ the enumeration of only ten guṇas (3.111),⁴²² and the recognition of a large number of vīryas (4.1 and 27).⁴²³ Remarkable is the absence of a discussion on prabhāva, which is an important notion in the *Carakasaṃhitā* and other texts. Anupānas are of six types, dependent on their action: āhārasātma, āhāravīyaghna, āhāraṇulomana, āhāraiviparīta, āhāraśodhana, and āhāraprajaraṇīya.⁴²⁴ The pramāṇas (means of acquiring valid knowledge) recognized are pratyakṣa, anumāna, upamāna, āgama, arthāpatti, and sambhava (4.70).⁴²⁵
