Bhagavad Gita 18.68

य इमं परमं गुह्यं मद्भक्तेष्वभिधास्यति।भक्ितं मयि परां कृत्वा मामेवैष्यत्यसंशयः॥

ya imaṃ paramaṃ guhyaṃ madbhakteṣvabhidhāsyati |bhakिtaṃ mayi parāṃ kṛtvā māmevaiṣyatyasaṃśayaḥ ||

He who, with supreme devotion to Me, teaches this supreme secret to My devotees, shall undoubtedly come to Me.

But he who teaches this great secret to My devotees, his is the highest devotion, and he shall surely come to Me.

Our plain-language meaning of this verse is waiting for scholar review.
