Amituo means infinite. Fo means Buddha. Everything, infinite wisdom, ability, long life, etc. But of all infinities, infinite life is the most important for without it all other infinities are useless. With it, we can enjoy all other infinities.
Infinity is none other than our self-nature, our original true nature.
In other words, it means infinity. We practice the teachings of Guan Yin Bodhisattva and Great Strength Bodhisattva. Great Strength Bodhisattva taught us Concentrate solely on Buddha Amitabha, without ceasing, without intermingling with other methods, and in this way we will surely attain wisdom and enlightenment . Adding to this is the compassionate way of Guan Yin Bodhisattva. Behaving towards others with compassion and chanting only Namo Amituofo will enable us to enjoy infinite life.
