भक्त्या त्वनन्यया शक्यमहमेवंविधोऽर्जुन ।ज्ञातुं दृष्टुं च तत्त्वेन प्रवेष्टुं च परंतप ॥
bhaktyā tvananyayā śakyamahamevaṃvidho'rjuna |jñātuṃ dṛṣṭuṃ ca tattvena praveṣṭuṃ ca paraṃtapa ||
But through single-minded devotion alone, O Arjuna, can I, in this form, be known, seen in truth, and entered into, O scorcher of foes.
Explanation
Krishna is concluding his teaching after showing Arjuna his universal form, and he says that the Vedas, austerity, giving and ritual cannot bring this vision (as in the previous verse). Only undivided devotion (bhakti) can lead to knowing him, seeing him in truth (tattva), and entering into him. Traditions differ on "entering": Advaita commentators tend to read it as merging into the Self, while devotional schools read it as entering into loving union with the personal God.
