A wonderful method for receiving the blessings of all the Buddhas is to chant praises and requests to Avalokiteshvara, Buddha of Compassion.
And to recite his mantra OM MANI PEME HUM.
Avalokiteshvara is an enlightened being who is a manifestation of all Buddhas’ compassion. By relying sincerely upon Avalokiteshvara, the Buddha of Compassion, and reciting his mantra with strong faith, temporarily we will improve our realizations of all the stages of the path, especially our realization of great compassion, and ultimately we will attain supreme Buddhahood in Avalokiteshvara’s Pure Land.
The prayers booklet focusses on the Four-armed aspect of Avalokiteshvara. It is very blessed; the main body of the prayers was composed by the great Tibetan Yogi Drubchen Tangtong Gyalpo, with additional prayers added by Geshe Kelsang Gyatso.
