B.G 18.68 to 71

ya idaṃ paramaṃ guhyaṃ madbhakteṣvabhidhāsyati। bhaktiṃ mayi parāṃ kṛtvā māmevaiṣyatyasaṃśayaḥ ॥68॥

na ca tasmānmanuṣyeṣu kaścinme priyakṛttamaḥ। bhavitā na ca me tasmādanyaḥ priyataro bhuvi ॥69॥

adhyeṣyate ca ya imaṃ dharmyaṃ saṃvādamāvayoḥ। jñānayajñena tenāhamiṣṭaḥ syāmiti me matiḥ ॥70॥

śraddhāvān anasūyaś ca śṛṇuyād api yo naraḥ। so'pi muktaḥ śubhān lokān prāpnuyāt puṇya karmaṇām ॥71॥

He who will speak this supreme secret to my devotees, having done supreme devotion to me, will come to me without doubt. And among men, there is no one dearer to me than he, nor will there be anyone dearer on earth. Whoever studies this sacred dialogue of ours through the sacrifice of knowledge, I shall be pleased by him; this is my opinion. A faithful and non-envious man who may hear, he too, being liberated, may attain the auspicious worlds of pious deeds.
