Negative States Drain Force
Try to see for yourself by direct observation how a negative state drains force from you and try to see what happens when, having observed your condition, you genuinely try to separate from this state for your own private reasons and not for the sake of being congratulated or to gain merit.
If you do this rightly you will feel a shock, you will experience the sensation that you have suddenly escaped from something evil, something that you did not realize was evil. Then you will begin to understand why it is said that we can detect the presence of negative states by means of inner taste.
