The augment ruṭ is diversely applied in the chandas (Vedas).,
Thus देवा अदुह्र; गन्धर्वा अप्सरसो अदुह्र ॥ Here अदुह्र is the Imperfect (लङ्) plural of दुह् ॥ Thus दुह् + झ = दुह् + रत् = अदुह्र, the त् being elided by 7.1.41. Sometimes, the augment does not take place, as अदुह्रत ॥ Owing to the word बहुल, 'diversely', the augment र is added to other affixes also, than झ ॥ As अदश्रम् in अदश्रमस्य केतवः ॥ This is the aorist in अङ् of the root दृश by 3.1.57, the guna ordained by 7.4.16, does not 'diversely' take place.,
