The affix leṭ (Vedic Subjunctive) is optionally used the chandas (Vedas) wherever the liṅ (Benedictive) can be used.,
Thus in the sense of 'command' &c., he may be employed instead of लिङ्. This is called the Vedic Subjunctive and is peculiar to the Vedas only. Thus जोषिषत् (Rig. II. 35. 1) 'may he make us beautiful'. तारिषत् (Rig. I. 25. 12) 'may he increase'. पताति विद्युत् (Rig. VII. 25. 1) 'may the thunder-bolt fall'. भवाति (Rig. V. 37.5) 'may he become'. So also मन्दिषत्, नेता, नेषत्, तक्षिषत्, उदधिं च्यावयाति ।,
