भीष्मविक्रमदर्शनं तथा क्रौञ्चारुणव्यूहविधानम् | Bhīṣma’s Ascendancy and the Organization of the Krauñcāruṇa Formation
य इमं परम॑ गुहां मद्धक्तेष्वभिधास्यति । भक्ति मयि परां कृत्वा मामेवैष्यत्यसंशय:
ya imaṁ paramaṁ guhyaṁ mad-bhakteṣv abhidhāsyati | bhaktiṁ mayi parāṁ kṛtvā mām evaiṣyaty asaṁśayaḥ ||
Whoever expounds this supreme secret among My devotees—having established the highest devotion toward Me—will come to Me alone, without doubt.
अजुन उवाच
Teaching the highest confidential doctrine to those who are devoted is itself an act of supreme devotion; such a teacher, grounded in bhakti, is assured of attaining the Lord.
In the Bhīṣma Parva’s Bhagavadgītā setting on the battlefield, the discourse turns to the fruit of sharing the teaching: the speaker promises that one who explains this supreme secret among devotees, with highest devotion, will certainly reach Him.
