I will try a technique or way of doing something. If it works for me I will keep doing it. If not I will not.
If I hear of an interesting belief I will check to see if there is evidence for it. If so, I will think about it more. If not, I will forget about it.
In reading the scriptures, there are two kinds of mistakes:
One mistake is to cling to the literal text and miss the inner principles.
The second mistake is to recognize the principles but not apply them to your own mind, so that you waste time and just make them into causes of entanglement.
