Bhagavad Gita 6.4 — Sign of one established in yoga
यदा हि नेन्द्रियार्थेषु न कर्मस्वनुषज्जते। सर्वसङ्कल्पसंन्यासी योगारूढस्तदोच्यते ॥
yadā hi nendriyārtheṣu na karmasvanuṣajjate | sarvasaṅkalpasaṃnyāsī yogārūḍhastadocyate ||
Meaning
When a person is attached neither to sense objects nor to actions, and has given up all selfish intentions, he is said to have reached yoga.
