The following is an excerpt from “Treasury of Precious Qualities: A Commentary on the Root Text of Jigme Lingpa” by Longchen Yeshe Dorje, Kangyur Rinpoche
…the tantra nam mkha’i klong yangs kyi rgyud says:
Meditation on the teacher
Is meditation on the Dharmakaya,
Compared with this, all meditation
On a hundred thousand deities
Is seen as nothing,
Therefore every act
Of wholesome Dharma–
Hearing, teaching
Meditating, and upholding,
Torma offerings and all the rest–
Are but preparations for the guru yoga.
For the teacher is the glorious Buddha
Of past, present, and all future time.
Om Mani Pedme Hung
So much emphasis is on Teacher that Guru is First and foremost. Guru shows the Path,maintains on the Path and Delivers
Meditation on the Teacher is a Bliss
Your Wisdom !!!
