As a result of these and other events, it was determined that Machig Labdron's Chod teachings were indeed authentic, and established that her Chöd teachings were the first Buddhist teachings to emerge in Tibet. One source says, "Word of the widespread practice of Mahāmudra Chö in Tibet and Nepal was first viewed in India with great scepticism. A delegation of ācāryas was sent from Bodh Gayā to Tibet to test Machig Labrön and her teaching resulted in the acceptance of Mahāmudrā Chö as a valid and authentic Mahāyāna tradition. Thereafter, its practice spread even to India."
