Bhagavad Gita Chapter 18, Verse 68
य इमं परमं गुह्यं मद्भक्तेष्वभिधास्यति | भक्तिं मयि परां कृत्वा मामेवैष्यत्यसंशयः ||
ya imaṁ paramaṁ guhyaṁ madbhakteṣv abhidhāsyati bhaktiṁ mayi parāṁ kṛtvā mām evaiṣyaty asaṁśayaḥ
He who explains this supreme secret among My devotees, having shown supreme devotion to Me, will come to Me alone, without doubt.
Krishna explains who will be liberated. 'Ya imaṁ paramaṁ guhyaṁ madbhakteṣv abhidhāsyati'—he who (yaḥ) explains (abhidhāsyati) this supreme secret (imam paramam guhyam) among My devotees (mat-bhakteṣu). 'Bhaktiṁ mayi parāṁ kṛtvā mām evaiṣyaty asaṁśayaḥ'—having shown (kṛtvā) supreme devotion (parām bhaktim) to Me (mayi), will come (eṣyati) to Me alone (mām eva), without doubt (asaṁśayaḥ). This is the assurance: whoever explains this supreme secret teaching to devotees, showing supreme devotion to Krishna, will certainly come to Krishna alone. This is the reward for sharing this teaching with devotees: you show supreme devotion by sharing it, and you will certainly come to the Supreme. This emphasizes the importance of sharing this teaching with devotees.
