By the grace of Śrī Vyāsa, I have heard this supremely confidential science of yoga explained personally by the all-attractive Śrī Kṛṣṇa Himself, the Lord of the yoga process.

Commentary: Sārārtha-Varṣiṇī Prakāśikā-vṛtti

(By Śrīla Bhaktivedānta Nārāyaṇa Gosvāmī Mahārāja; the explanation that illuminates the commentary named Sārārtha-varṣiṇī)

Śrī Kṛṣṇa Dvaipāyana Vyāsadeva was the guru of Sañjaya. Sañjaya acknowledges that he heard and understood the divine knowledge of Śrīmad Bhagavad-gītā, which manifested from the dialogue between Kṛṣṇa and Arjuna, only by the grace of his guru. Without the grace of guru, the truth (tattva) of the Bhagavad-gītā or of Bhagavān cannot be understood. The guru must be as well-versed in tattva and as endowed with realization of Bhagavān as Śrīla Vyāsadeva himself. And the disciple should be like Sañjaya, capable of rendering attentive service to the guru, desiring to hear from him and to follow his teachings and instructions without argument. Only such a faithful disciple can understand bhagavat-tattva and achieve complete perfection. It should also be understood that, just as Arjuna became supremely blessed after hearing the deep secret of the Bhagavad-gītā directly from the lotus mouth of Svayam Bhagavān Śrī Kṛṣṇa, Sañjaya also, by the grace of Śrīla Vyāsadeva, became supremely blessed upon hearing and understanding it, although he was sitting far away from Kurukṣetra. And just as Arjuna and Sañjaya were blessed and became perfect, any person, even now, who wants to make his life blessed can do so by taking bath in the philosophical current descending through the bona fide disciplic succession (guru-paramparā) and surrendering to a self-realized guru or Vaiṣṇava. It is very difficult to attain bhagavat-tattva unless one accepts a disciplic succession of those who establish pure devotion in this world.
