Sings Bhagavad Gita:

तद्विद्धि प्रणिपातेन परिप्रश्नेन सेवया ।
उपदेक्ष्यन्ति ते ज्ञानं ज्ञानिनस्तत्त्वदर्शिनः ॥४-३४॥

tad viddhi praṇipatena
paripraśnena sevayā,
upadeksyanti te jñānam
jñāninas tattvadarśinaḥ

 Seeker is advised to approach seers with reverence, self-surrender, and humility, to be instructed in true knowledge through devoted service and guileless curiosity. These seers will enlighten him/her on it. The ability to acquire this knowledge comes only with a wholly dedicated service. They are seers who enable us to have direct perception of God. They know the mode of yagya and they will teach it to true seeker.

Only totally accomplished and fully enlightened sages can lead in traversing upon the “Path of Self Realization”
because they have acquired this knowledge 
through Self awareness.

Humble Wishes!!!
