Guru Gyan Vani / गुरु ज्ञान वाणी

Tad viddhi pranipatena

pariprasnena sevaya

upadeksyanti te jnanam

jnaninas tattva-darsinah

Gita 4-34

To understand that knowledge, by going to the Tatvdarshi, by bowing down to them thoroughly, by serving them, and by simply asking questions without deceit, then those Mahatmas, who know the Supreme Soul and wisdom well, will instruct you on that principle.

Having a Guru who has all the qualities means that one got everything in life. To give proper guidance on any subject is the quality of a true and experienced scholar. Some part of such Guru's wisdom is given in this book.
