Meaning (brief): Mantrapushpanjali is a Vedic hymn traditionally recited at the very end of a puja while offering flowers to the deity. It invokes universal sovereignty and long life — through Kubera/Vaishravana, the "king of kings" — and closes with the Ganapati beeja mantra ("Ekadantaya vidmahe, vakratundaya dhimahi...", roughly "we meditate on the one-tusked lord..."). The word-for-word sense of some of this archaic Vedic prose is debated even among scholars — what's given here is the traditionally understood gist.
The words and tune can vary slightly by household or sect.
