Bhagavad Gita 14.22

Lord Shri Krishna replied: O Prince! He who does not shun the quality that is present and does not long for that which is absent;

श्री भगवानुवाचप्रकाशं च प्रवृत्तिं च मोहमेव च पाण्डव।न द्वेष्टि सम्प्रवृत्तानि न निवृत्तानि काङ्क्षति॥

śrī bhagavānuvācaprakāśaṃ ca pravṛttiṃ ca mohameva ca pāṇḍava|na dveṣṭi sampravṛttāni na nivṛttāni kāṅkṣati||
