Śrīmad-Bhāgavatam · Text 11.21.19
Who is speaking and story frame
विषयेषु गुणाध्यासात् पुंस: सङ्गस्ततो भवेत् ।
सङ्गात्तत्र भवेत् काम: कामादेव कलिर्नृणाम् ॥ १९ ॥
viṣayeṣu guṇādhyāsāt
puṁsaḥ saṅgas tato bhavet
saṅgāt tatra bhavet kāmaḥ
kāmād eva kalir nṛṇām
One who accepts material sense objects as desirable certainly becomes attached to them. From such attachment lust arises, and this lust creates quarrel among men.
