The one whose activity is directed toward Kṛṣṇa — he is called here the tad-anvayī, the one 'connected to him.' The lead-in has just announced this class ('now, the tad-anvayī'); the line defines it by a single test: where the person's doings point. If they point at Kṛṣṇa, he counts as connected to him.
जिसकी चेष्टा कृष्ण को विषय करती है, वह पुरुष यहाँ 'तद्-अन्वयी' (कृष्ण से सम्बद्ध) कहा गया है।
