Verse
अश्रद्दधानाः पुरुषा धर्मस्यास्य परंतप ।अप्राप्य मां निवर्तन्ते मृत्युसंसारवर्त्मनि ॥
(But faith is necessary). The souls that fail to get faith in the higher truth and law, O Parantapa, not attaining to Me, must return into the path of ordinary mortal living (subject to death and error and evil).
Gītā 9·3
