यदा हि नेन्द्रियार्थेषु न कर्मस्वनुषज्जते । सर्वसंकल्पसंन्यासी योगारूढस्तदोच्यते ॥४॥
yadā hi nendriyārtheṣu na karmasv anuṣajjate sarva-sańkalpa-sannyāsī yogārūḍhas tadocyate
yadā — when; hi — certainly; na — not; indriya-artheṣu — in sense gratification; na — never; karmasu — in fruitive activities; anuṣajjate — one necessarily engages; sarva-saṅkalpa — of all material desires; sannyāsī — renouncer; yoga-ārūḍhaḥ — elevated in yoga; tadā — at that time; ucyate — is said to be.
When one is neither attached to sense objects nor to actions, that person is said to be elevated in the science of Yog, for having renounced all desires for the fruits of actions.
When a person is fully engaged in the transcendental loving service of the Lord, he is pleased in himself, and thus he is no longer engaged in sense gratification or in fruitive activities. Otherwise, one must be engaged in sense gratification, since one cannot live without engagement. Without Kṛṣṇa consciousness, one must be always seeking self-centered or extended selfish activities. But a Kṛṣṇa conscious person can do everything for the satisfaction of Kṛṣṇa and thereby be perfectly detached from sense gratification. One who has no such realization must mechanically try to escape material desires before being elevated to the top rung of the yoga ladder.
