The Concluding Promise
Phalaśruti (Sanskrit: phala = fruit/reward + śruti = hearing/declaring) is the concluding verse of many Vedic, Purāṇic, and devotional compositions that states the blessings accruing to those who recite, hear, or study the text. It functions as a seal on the text and an encouragement to devoted recitation.
In the Divya Prabandham
Most prabandhas of the Nālāyira Divya Prabandham conclude with a phalaśruti — the Āzhvār declares the benefit: liberation, Bhagavān's presence, protection from evil, success in devotion, etc. For example, Nammāzhvār's Tiruvāymozhi concludes with the declaration that those who recite it will attain Bhagavān's company in Vaikuṇṭha.
Theological Significance
The phalaśruti is not mere encouragement — it is an Āzhvār's guarantee, backed by their direct vision of Bhagavān (divya-maṅgala-vigraha). When the Āzhvār declares 'those who sing this will be free,' it is a statement of fact grounded in the Āzhvār's own experience and Bhagavān's will.
