By Swami Harshananda
Āhāva literally means ‘calling’.
Derived from the root ‘hve’ (‘to call’), āhāva is the technical name of a formula of summons pronounced loudly by the hotṛ (chief of the priests representing the Rgveda) in a Soma sacrifice before starting the śastra (laudatory recitation). It is usually in the form of śom 3* sāvom or śoṃsāvo 3 (a corrupt form of śarṃsāva).
- Morning - prātasavana
- Noon - mādhyandinasavana
- Evening - tṛtīyasavana
During all these three savanas āhāva is done 4 times in the first, 5 times in the second and again 4 times in the third.
- The numeral 3 indicates that the syllable is to be chanted for 3 unites of time, called a 'pluta' as against 1 unit of time ('hrasva') or 2 units of time (dīrgha').
