[Of] all Dharma Doors,
[they] all rely [upon] Self-Power.
[The] Dharma Door [of] mindfulness [of] Buddha,
simultaneously relies [upon] Buddha‘s power.
Pure Land Tradition’s 13th Patriarch Great Master Yìnguāng
(Wúxī Buddhist Pure Land Practice Society‘s Annual’s Preface)
It is already very difficult to rely upon only Self-Power (自力) for liberation in this lifetime, what more to attain Buddhahood. As all Dharma Doors rely upon Self-Power, the Two-Powered (二力) Pure Land path does too. However, it combines Self-Power with the Other-Power (他力; 佛力) of Āmítuófó (阿弥陀佛: Amitā[bha] Buddha) for the crucial connection and support to reach his Pure Land, thus enabling swiftest progress towards Buddhahood. With interconnection to all other Buddhas, this Other-Power is all Buddhas’ united power of blessings too.
