Garab Dorje transmitted Maha Ati to various Indian masters including Manjusrimitra, who obtained instant realization simply by observing a gesture of “direct introduction” from his master. Garab Dorje wrote the following teaching:
Mind’s nature is Buddha from the beginning.
It has neither birth nor cessation, like space.
When you realize the real meaning of the equal nature of all things,
To remain in that state without searching is meditation.
Manjusrimitra then expressed his understanding of this instruction:
I Am Manjushrimitra
I have attained the accomplishment of Yamantaka.
I have realized the great equality of samsara and nirvana;
Omniscient primal wisdom has arisen. {{5}}
