When the Living Buddha[r_4:15] Mi-rgyur-rdo-rje (Immutable Vajra), was eleven years old, he captured entirely by intuition thirteen volumes of the Treasury of Dharma from Heavenly Sources[r_4:16] within three years. Afterward he also received this one volume of the Treasury of Percipience. Although there was an indication that he might have captured another one hundred volumes from the Treasury of Earth, he did not receive any due to unfavourable influences. His external life was ill-omened. By the age of seventeen, he had completed his work on the Treasury of Percipience. In one of his books of Initiation, this volume was found. As said in the Sutra of the Emerging of Pure Dharma, Chos-yan-dag-par-sbjun pahi-mdo:

"There will come a few Bodhisattvas of pure mind and heart who, merely through the observation of their own

consciousness, will obtain the inner teachings and the principles of Dharma (the law or nature of reality); from them these inner teachings of Dharma will thence be imparted to the people."

This is evidence that the tradition of the Dharma from Treasury finds support in the Sutras.

Furthermore, the Dharma from Treasury[r_4:17] is deeper and more profound than the Dharma from Mouth[r_4:18] (preaching). The Treasury from Heaven[r_4:19] is more profound than the Treasury from Earth[r_4:20]. Again, the Treasury of Percipience is more profound than the Treasury From Heaven.

The benefits to the devotee who practices the Yoga of Hayagriva were stated in The Manifestation of the Superb Victorious Wrathful Great Horse Tantra:

"To the superb Initiation of the Fierce Hayagriva
And the victorious Tantra of great value!
If one surely beholds the initiation and has a fancy for it, he will be emancipated from fear and all diseases.
Those who practice the Yoga of Hayagriva, their patron Buddha,
Will be immune for seven hundred births from falling into the lower path and hell.
Those who have the faith and the pure realization constantly,
Will in their future life be born in the Pure Land.
If one recites each word of incantation 100,000 times,
Right in this life he shall see the face of Hayagriva.
Even in offering a part of the offerings to the Lord,
He will influence his surroundings and his neighbors.
Those who merely recite the incantation frequently
Will be free from the afflictions caused by evil spirits."

So it is said in this Sutra.

The Tantra of Proud Master Hayagriva states:

"Those who practice the Yoga of Hayagriva will attain the Common and the Eight Superb Accomplishments. They will also obtain the Four Accomplishments of the Illumination-Holding[r_4:21] (Yogi). He who does this will likewise attain the Three Bodies, the Four Bodies, the Five Bodies, and so on. He will also attain the Accomplishment of Mahamudra."
