I am looking to learn and get initiation into Dzogchen eventually leading into Tögal and trekchö. Coming from a Indian yogic tradition the rainbow body of perfection is the pinnacle of yogic achievement. I would consider it an honour to get initiated under a master in an accomplished lineage for this purpose alone.
Also any good books that discuss the rainbow body and the dzogchen practices such as chord, trechko and togal will be immensely useful. Please give me suggestions.
