prajñā-vardha
The Awakening of Wisdom
Instantly enter into Manjushri yoga. Above the lunar disc at the navel, visualize a white bindu accompanied by a ray of light resembling the glow of an oil lamp. [Visualize] the white syllable haṁ in the crown of the head, free from any blemishes. Meditate that [nectar] drips from [his] head along with a ray of light.
Thereafter, the [syllable] is stimulated by the ray of light from the bindu. Through this, it transforms into a seed, and by means of the syllable haṁ, the bindu pervades everywhere. A mantric practitioner with a steady mind will indeed increase wisdom without adhering to a long [retention period].
Such is the manifest generation of wisdom.
Translated by Tsultrim Gyaltsen based on [the instructions] of Abhaya.
Translated by Lama Dondrub Dorje Tulku.
