Sanskrit:
तप:सत्यदयादानेष्वर्धं ह्रस्वति द्वापरे ।हिंसातुष्टयनृतद्वेषैर्धर्मस्याधर्मलक्षणै: ॥ २२ ॥
ITRANS:
tapaḥ-satya-dayā-dāneṣvardhaṁ hrasvati dvāparehiṁsātuṣṭy-anṛta-dveṣairdharmasyādharma-lakṣaṇaiḥ
Translation:
In Dvāpara-yuga the religious qualities of austerity, truth, mercy and charity are reduced to one half by their irreligious counterparts — dissatisfaction, untruth, violence and enmity.
