Let’s say you have eaten a tasty snack, or secured a top rank, or won an award, or served a hungry child, or donated a fund for covid-19 relief.
If your mind thinks that the experience is a result of your own efforts and starts feeling proud of the achievement forgetting the role of “invisible” supreme soul in the entire framework, then your mind needs cleansing.

Until the mind has the wisdom to do this, it will succumb to incorrect interpretations of the situations and puts you in trouble, sooner or later.
