Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 41

Sanskrit:

देवदत्तमिमं लब्ध्वा नृलोकमजितेन्द्रिय: ।यो नाद्रियेत त्वत्पादौ स शोच्यो ह्यात्मवञ्चक: ॥ ४१ ॥

ITRANS:

deva-dattam imaṁ labdhvānṛ-lokam ajitendriyaḥyo nādriyeta tvat-pādausa śocyo hy ātma-vañcakaḥ

Translation:

One who has attained this human form of life as a gift from God, yet who fails to control his senses and honor Your feet, is surely to be pitied, for he is only cheating himself.

Purport:

Lord Śiva here condemns those who refuse to engage in the devotional service of the Supreme Lord.
