and the word anuśaya is clearly a kṛt formation as it ends with the affix ach[61] [which brings it under this prohibition, and so renders it insusceptible of the affix ini]. Consequently, the word anuśayin in the Yoga aphorism is one the formation of which it is very hard to justify."[62] This cavil, however, is not to be admitted; since the rule is only to be understood as applying generally, not absolutely, as it does not refer to something of essential importance. Hence the author of the Vṛtti has said—

"The word iti, as implying the idea of popular acceptation, is everywhere connected with the examples of this rule[63] [i.e., it is not an absolute law]."

Therefore, sometimes the prohibited cases are found, as kāryin, kāryika [where the affixes are added after a kṛt formation], taṇḍulin, taṇḍulika [where they are added after a word meaning "genus"]. Hence the prohibition is only general, not absolute, after kṛt formations and words meaning "genus," and therefore the use of the affix ini is justified, although the word anuśaya is formed by a kṛt affix. This doubt therefore is settled.
