The sins committed by the sense-buried affect generations, back and forth, c.f. Hanumān’s advice to Rāvaṇa, that one of the latter’s calibre and wisdom should desist from committing sins which shall destroy the entire race. The Āzhvār wants the Lord to dower on him the strength which will make him tougher than this tough fountain-source of all sins, so as to demolish it effectively.
