In direct and experiential language, Dzogchen Pema Kalsang Rinpoche explains clearly how to put Shabkar's classic verses on trekchö meditation into practice, so we may realise the true nature of mind. These profound instructions may only be read by those who have been authorised and empowered into the main Dzogchen practices by a genuine master. "For a living breathing human being, is there anyone to whom thoughts do not arise? Thoughts occur, but it does not matter. Thoughts are the dynamic energy of true nature. If they arise, allow them to arise. If they do not occur, allow them not to occur. When abiding, this is the essence of true nature. When thoughts stream forth, this is the manifest dynamic energy of wisdom. Do not pursue thoughts. If we chase after them we become confused, like water turning into ice. Leave thoughts naturally and they become self-liberated. Unload the mental burden of activities and remain in unwavering equipoise of effortless non-meditation." One of the most eminent lamas in Tibet, Dzogchen Pema Kalsang Rinpoche is widely recognised as a brilliant scholar and highly realised master of the Great Perfection. His insight brings an authenticity to the teachings which can only be present in the words of a realised master.
