Some people, being spiritually self-satisfied, do not reciprocate others’ affection because they want to avoid entanglement in mundane dealings. Other persons do not reciprocate simply out of envy or arrogance. And still others fail to reciprocate because they are materially satisfied and thus uninterested in new material opportunities. Lord Kṛṣṇa patiently explains all these things to the gopīs.
