Amitabha.
First of all, we must first understand what cause and effect and reincarnation are. Cause and effect spans three lives. This life has a close and direct relationship with the previous life and the next life.
This verse is divided into two sentences. Predict the causes of past lives and what you will suffer in this life. That is to say, if you want to know what it was like in your previous life, you will understand by looking at the consequences you received in this life. For example, if you are poor in this life, then theft must have been caused by the past life. If you are not good-looking in this life, then you must be angry and caused the consequences in the previous life. If you are ignorant in this life, there must be reasons for slandering the Three Jewels in the previous life, and so on.
Foretell the consequences of the next life and what you do in this life. The consequences in the future will all depend on what you do in this life. What you do in this life is the cause, and you will bear the consequences in the next life. Making more offerings to the Three Jewels is the cause of wealth. Being equal to people and not looking down on them is the cause of good karma. Being pleasant to people and not losing your temper is the cause of having a majestic appearance. Taking refuge in the Three Jewels is the cause of wisdom and liberation.
That's generally true. Let’s experience it.
