The Bhikṣuṇī Maṇimēkhalai

279 - Buddhist Logic
before one may be taken to be either vapour or mist, it is actually
taken to be smoke, and from that, the conclusion is drawn that there
must be fire behind.
(4) Āṣraya-siddham is to prove to the opponent the non-existence of
the Dharmin or the middle term as when one states that
Ether (or ākāśa) is a substance
Because it has the quality of sound,
the conclusion is unproved to him who believes that ether is not a
substance.
Anaikāntikam similarly is of six forms:–
(1) Sādhāraṇa;
(2) Asādhāraṇa;
(3) Sapakkaikadēśaviruddhavipakkavyāpi;
(4) Vipakkaika dēśaviruddhacapakkavyāpi;
(5) Upayaikadēśaviruddha and
(6) Viruddhavyabhicāri.
Of these, Sādhāraṇa consists in the common hētu or middle term
being uncertain, both in the Sapakṣa and in the Vipakṣa (a similar and
the counter case), as in the example:–
Sound is non-eternal
Because it is cognizable.
The quality of cognizability is a common quality of things eternal and
things non-eternal. It is cognizable to be non-eternal as in the case of a
pot, a product; it is cognizable to be eternal as in the case of ether.
