The word “Anjali” means “an offering”. Thus offering can be made in various ways. The most commonly heard is pushpanjali ie an offering with “pushpam” meaning flowers, Geetanjali an offering of a song that is geetam, Swaranjali an offering of music, Shraddhanjali an offering of love.
In this context Pushpanjali is an offering of flowers by the dancer. It is an invocation piece done at the beginning of a performance. Sometimes a shlokam is also incorporated into it. Shlokam can be in praise of any deity. Pushpanjali that I have explained here is most commonly seen with the students of Kalakshetra Lineage.
