Chapter XI · Śloka 54
भक्त्या त्वनन्यया शक्य अहमेवंविधोऽर्जुन |
ज्ञातुं द्रष्टुं च तत्त्वेन प्रवेष्टुं च परन्तप ||
ज्ञातुं द्रष्टुं च तत्त्वेन प्रवेष्टुं च परन्तप ||
bhaktyā tv ananyayā śakya aham evaṃ-vidho 'rjuna |
jñātuṃ draṣṭuṃ ca tattvena praveṣṭuṃ ca parantapa ||
jñātuṃ draṣṭuṃ ca tattvena praveṣṭuṃ ca parantapa ||
But by undivided devotion alone, O Arjuna, I can be known, truly seen, and entered into, O scorcher of enemies.
The single key: ananyā bhakti — undivided devotion, love that does not wander. Not knowledge that stands apart and analyses, but love that moves toward and enters. The three stages — knowing, seeing, entering — describe a single progressive intimacy.
