Srimad-Bhagavatam: Canto 8 - Chapter 1 - Verse 33
Sanskrit:
वृथा मनोरथस्तस्य दूर: स्वर्ग: पतत्यध: ।प्रतिश्रुतस्यादानेन योऽर्थिनं विप्रलम्भते ॥ ३३ ॥
ITRANS:
vṛthā manorathas tasyadūraḥ svargaḥ pataty adhaḥpratiśrutasyādānenayo ’rthinaṁ vipralambhate
Translation:
Far from being elevated to the heavenly planets or fulfilling one’s desire, one who does not properly give a beggar what he has promised falls down to a hellish condition of life.
