The transformation of Non-Finite verbs is fairly straightforward, and the resulting term is considered an Indeclinable in Sanskrit. An auxiliary vowel 'i' may be need to be inserted between the verb root and the affix. This is governed by the nature of the verb i.e. whether it is a 'seT' root (i.e. expects an 'i' auxiliary vowel), an 'aniT' root (does not accept an 'i' auxiliary vowel), or a 'veT' root (an optional 'i' auxiliary vowel).
An example of an infinitive can be seen in Stanza 1.35 'I do not wish to kill these ...'.
The affix 'tum' (known as a 'तुमुन्' affix in the Ashtadhyayi) is attached to the verb root (an intervening auxiliary vowel 'i' may be required for 'seT' roots).

There are two affixes for gerunds in Classical Sanskrit.
An example of both forms can be seen in Stanza 1.2 'Having seen ... having approached the preceptor ...'.When a verb does not have an 'upasarga' prefix (akin to prepositions in English), the affix 'tvA' (known as the 'क्त्वा' affix in the Ashtadhyayi) is attached to the verb root (an intervening auxiliary vowel 'i' may be required for 'seT' roots).
