Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 32

Sanskrit:

असन्तुष्टोऽसकृल्ल‍ोकानाप्नोत्यपि सुरेश्वर: ।अकिञ्चनोऽपि सन्तुष्ट: शेते सर्वाङ्गविज्वर: ॥ ३२ ॥

ITRANS:

asantuṣṭo ’sakṛl lokānāpnoty api sureśvaraḥakiñcano ’pi santuṣṭaḥśete sarvāṅga-vijvaraḥ

Translation:

An unsatisfied brāhmaṇa wanders restlessly from one planet to another, even if he becomes King of heaven. But a satisfied brāhmaṇa, though he may possess nothing, rests peacefully, all his limbs free of distress.

Purport:

Those who are unsatisfied feel distress throughout their body, becoming subject to many diseases. A satisfied brāhmaṇa, however, though he may possess nothing, is peaceful and calm, and there is no distress within his body or mind.
