Divine Speech
Śrī Sūkti (Sanskrit: śrī = auspicious/divine + sūkti = well-spoken words) refers collectively to the verbal compositions of the Āzhvārs and Ācāryas — the pāsurams, stotra hymns, vyākhyānam passages, and cūrṇais that constitute the living textual heritage of the Śrī Vaiṣṇava tradition.
Why 'Auspicious'?
The words of an Āzhvār or Ācārya are śrī sūkti because they originate from Bhagavān's direct inspiration rather than ordinary human learning. The Āzhvārs were granted divine vision (divya-jñāna) by Bhagavān's grace; their words therefore carry His intention. Ācāryas who composed within the sampradāya tradition are similarly regarded as transmitting Bhagavān's will through their śrī sūktis.

To quote a Ācārya's teaching, a practitioner says 'as per the śrī sūkti of...' (...aruḷicceyal). The phrase 'as per our poorvācāryas' śrī sūktis' (pūrvācāryarkaḷ śrī sūktipadi) is a common formulation in doctrinal discussion, indicating that the point is backed by the authorized textual tradition.
