In Mahayana Buddhism, especially the Sukhavati or Pure Land Sect, Amitabha Buddha is always said to be the compassionate Father of all sentient beings.
Once I've ever heard about this from a Dharma VCD. The speaker of the Dharma VCD was a monk. He said that we as Buddhist practitioners of the Pure Land Sect should recite the Buddha'name with utmost sincerity. When your life in this world has come to its end, where would you return?
