You Are the Eyes of the World

AA: This one is You Are the Eyes of the World by Longchenpa.

If you glance at it, even the explanation of the Guru Yoga is very advanced and requires a very strong faith and understanding.

PKV: hahaha! I had a brief glance through Mahayoga - Guru yoga.

Practicing a Fortnight the way they explained & you see results, sounded so easy!

Frankly speaking, for those with what Shizun says "Da gen qi 大根器 Great Roots", it might be possible. :)

The Foundation needed to be well laid though to achieve what they describe in 14 days!

Technique is very good provide the cultivator has Great Inherent Potential!

Yup! It is an advance method of Guru Yoga whereby the cultivator has already built up Resources required! :) 

Thanks for sharing.
