ChNNR mentions two Longde root tantras in his book Longde Teachings, Longchen Rabjam Gyalpoi Gyud/The King of the Infinite Universe and Namkha Tang Nyampai Gyud/Equal to Space. Has anyone here ever read these? I am curious as to their length and if they have been translated into English or not. Are they like Heart Sutra length or Lotus Sutra length? Also for those familiar with Longde Root Tantras and Longde practice, what in your opinion, out of all of the Longde tantras would be the most direct and pithy for study that would aid one in actual practice and understanding of Longde? Thank you all in advance for your help and insight into this.
