One who is in association with great acaryas, even if he is not educated or has not studied the Vedas, can become familiar with all the knowledge necessary for realization

Bhagavad-gita As It Is | Part [BG.9.05]

In the Vedanta-sutra (3.2.26) this is also described in the following words: prakasas ca karmany abhyasat. "Devotional service is so potent that simply by engaging in the activities of devotional service one becomes enlightened without a doubt." Narada, who happened to be the son of a maidservant, had no education, nor was he born into a high family. But when his mother was engaged in serving great devotees, Narada also became engaged, and sometimes, in the absence of his mother, he would serve the great devotees himself. Narada personally says, "Once only, by their permission, I took the remnants of their food, and by so doing all my sins were at once eradicated. Thus being engaged, I became purified in heart, and at that time the very nature of the transcendentalist became attractive to me."(Bhag 1.5.25) Narada tells his disciple Vyasadeva that in a previous life he was engaged as a boy servant of purified devotees during the four months of their stay and that he was intimately associating with them.

Sometimes those sages left remnants of food on their dishes, and the boy, who would wash their dishes, wanted to taste the remnants. So he asked the great devotees whether he could eat them, and they gave their permission. Narada then ate those remnants and consequently became freed from all sinful reactions. As he went on eating, he gradually became as purehearted as the sages, and he gradually developed the same taste. The great devotees relished the taste of unceasing devotional service of the Lord, hearing, chanting, etc., and by developing the same taste, Narada wanted also to hear and chant the glories of the Lord. Thus by associating with the sages, he developed a great desire for devotional service. Therefore, he quotes from the Vedanta-sutra (prakasas ca karmany abhyasat): if one is engaged simply in the acts of devotional service, everything is revealed to him automatically, and he can understand. This is called pratyaksa, directly perceived.

Narada was actually a son of a maidservant. He had no opportunity to go to school. He was simply assisting his mother, and fortunately his mother rendered some service to the devotees. The child Narada also got the opportunity and simply by association achieved the highest goal of all religions, devotional service. In the Srimad-Bhagavatam it is said that religious people generally do not know that the highest perfection of religion is the attainment of the stage of devotional service. Generally Vedic knowledge is required for understanding the path of self-realization. But here, although he was not educated in the Vedic principles, Narada acquired the highest results of Vedic study. This process is so potent that even without performing the religious process regularly, one can be raised to the highest perfection. How is this possible? This is also confirmed in Vedic literature: acaryavan puruso veda. One who is in association with great acaryas, even if he is not educated or has not studied the Vedas, can become familiar with all the knowledge necessary for realization.
