Nida Chenagtsang

“In order to benefit yogis and yoginis who are applying themselves diligently in the preliminary practices and guru yoga, like rivers of various sizes and lengths, that all flow down or condense together into one great ocean, I have written down the quintessential meaning of the practices and pointing-out processes of Ati Yoga, the ultimate embodiment of the meaning of meditation.”

“These practices show us that everything is energy–anger, jealousy, pride–these emotions are all energy. You let them arise and even if you start with anger or other ‘bad’ emotions, you end up with a happy result. That’s what Karmamudra is all about. You don’t say "stop having anger, stop feeling this or that emotion." Instead, you become the master of your emotions, you realize you can work with their energy and use it. That’s the essence of Vajrayana. Vajrayana is the indestructible vehicle. What is it that is indestructible? The non-dualistic mind is indestructible, the bliss of its nature, of pristine awareness is indestructible. Nothing can destroy that bliss–suffering, pain, anger, jealousy, pride, these and all other poisons are no match for it. Vajrayana or Tantric Buddhism thus offers very fine and precise teachings and methods that allow us to transform our emotions.”
