The Dispeller of Obstacles is the heart essence of the accomplished master Padmasambhava who perceives the three times in the entirity. It is the quintessence of one billion heart sadhanas of the Guru, the most unique terma buried in the land of Tibet; and it is the first among the Four Cycles of Guru Sadhana. This Guru's Heart Practice that Dispels all Obstacles contains in completeness all the profound key points of the view, meditation and conduct of the Three Inner Yoga Tantras. It manifested from the secret treasury of the great wisdom, the vast realization of the Second Buddha of Uddiyana, as the selfexisting natural vajra sounds in perfect melodious tones. Its expressions that are unmodified by the intellect of ordinary people, its words that are without delusion, and its meaning that is unmistaken, are exclusively due to the kindness of the three powerful knowledge Holders Khyentse, Kongtrul, and Chokling, the great beings of the three families, who incarnated as masters to compile and propagate an ocean of secret teachings. It is exclusively through their kindness that this teaching was established in writing as the splendor of unending welfare and happiness for the disciples in the Land of Snow and propagated to flourish everywhere.
