Parikṣāmukham
The Naiyayikas following Gautama also mention "Udaharaṇa is illustration following a mention of universal concomitance, e. g. whatever is full of smoke is full of fire as a kitchen. This is Sadharmya Udaharaṇa. Whatever is not full of fire is not full of smoke as a lake. This is an example of Vaidharmya Udāharaṇa1."
हेतोरुपसंहार उपनयः ॥ ५० ॥
50. Hetorupasamhāra upanayaḥ.
50. Upanaya is the application (asserting the existence) of the Hetu (in the Dharmi after a knowledge of concomitance).
Commentary
Upanaya is the description of the undoubted existence of the Hetu (e. g. smoke) in the Paksa (e. g. mountain) in concomitance2.
We have already mentioned the five parts of Anumana as adopted by Gautama viz. Pratijñā, Hetu, Udaharaṇa, Upanaya and Nigamana. Upanaya or application is used after Dristanta e. g. "So is this hill full of smoke."
