Dhyāna 3

In plain words

The place of the guru of the upward transmission, whose lion-throne is the three worlds called by the syllable oṃ; sung in the practice of the siddhas and in all the Vedas, moving through the six cakras; one, spotless, a fire flashing without a second, adorned with full radiance. Worship that, my mind: the lotus of Śrī Guru, the moonrise of awareness, at peace.
