As for the non-dual method, must there be only one method of faith?

Amitabha! Benevolent man, there are countless Dharma doors in the world, but the truth is the only one!

The so-called non-dual method refers to the most ultimate and perfect state of the Buddha's mind. Entering this state means understanding the Buddha's mind and achieving the ultimate Bodhi path and fruit. For our descendants to give a name to the Dharma door, it is actually better to say that it is the non-dual state, which is closer. It’s not that the laws are different, it’s that people’s hearts are different. Any method, as long as you believe in the right path, you can eventually achieve the ultimate Buddha mind state of the non-dual method.

This principle is profound and difficult to understand, and this path is difficult for ordinary people to enter. It cannot be understood by outsiders, the good Dharma of humans and gods, etc., nor can it be understood by the saints of the Two Vehicles. Only the Buddha can know it! The reason why the Buddha is a Buddha is precisely because of his ultimate and perfect enlightenment. Buddha is just a name. If you go deeper from other Dharma doors and can enter the realm, you will become a Buddha! Even the good practices of humans and gods in the world, as well as Jesus, Christ, Taoism, etc., as long as they can enter this ultimate and unique realm, they can all be called "Buddhas".

As for which practice method to choose, it depends on the reasons. Everyone's causes and conditions are different. Some achieve enlightenment on the earth, some on the water, some gain enlightenment by chanting the Buddha's name, and some gain enlightenment due to their perfect ears. As long as the cause and conditions suit you, you can use subtle methods to achieve enlightenment. By contemplating the principles, one can gain ultimate enlightenment, and the realms of enlightenment are the same. However, for us ordinary people, if we are greedy for more knowledge and explanations, cannot settle down, cannot observe rationally, and can enter into one door at a time, then we are like well diggers, digging a hole here and a pile of soil there, but in the end we will not be able to achieve anything. !
