The affixes luṅ (Aorist) comes after a verb when the word māṇ is used in connection with it.,
This sets aside all other tense-affixes. As मा कार्षीत् 'let him not do' मा हार्षीत् 'Iet him not take'.
How have we then the Imperative and the Future tenses in the following sentence instead of the Aorist ? मा भवतु तस्य पापं मा भविष्यति । This sentence is against good usage. Or, we may explain it by saying that there is another मा which has not the indicatory ङ; and with that मा, other tenses may be used. The augment is elided after the prohibitive participle मा, by 6.4.74.,
