仰底上師儀軌其實是近代至尊圖續法王的前一世──一世紀前著名的岩藏師東嘎林巴──所發掘的伏藏之一，然而基於多種因緣，此伏藏法并不廣傳。後來東嘎林巴的主要弟子札楚仁波切（雅旺東嘎滇津諾布究美確吉）重新發掘此伏藏法，再將這獨特的心要傳予其上師的轉世，即圖續法王。因此此仰底上師儀軌之傳承非常清新、清淨與直接，毫無破損三昧耶戒（金剛乘之戒律）之染污。
Yangti Guru ritual is actually one of the more recent termas (hidden treasures) unveiled by Kyabje Trulshik Rinpoche's previous incarnation, Dongak Lingpa, a revered terton one century ago. However this terma was not wide spread due to various reasons, and subsequently Dongak Lingpa's chief disciple Ngawang Dongak Tenzin Norbu Gyurme Chokyi or the very venerable Dzatrul Rinpoche re-discovered the terma and passed this unique terma lineage to his heart-disciple, Kyabje Trulshik Rinpoche, the reincarnation of his guru. Therefore this lineage of Yangti Guru ritual is considered to be very fresh, pure and direct, without contamination of broken samaya (Vajrayana vows).
修持仰底蓮師儀軌能讓我們體悟上師身語意之智慧，也讓我們理解上師之法、報、化身的總集相，因此是實現了悟自心本質的特別修法。
The practice of Yangti is essential for the realization of the Guru's Wisdom Body, Speech and Mind, which also includes the understanding of the Guru in Dharmakaya, Sambhogakaya and Nirmanakaya forms. It is a special practice which effects the realization of one's own nature of mind.
這獨特的儀軌中，蓮花生大士的心中顯現四臂觀音，而後者心中再現阿彌陀佛，三位皆為極樂淨土的主要本尊，是證悟三身的總集表徵。
