When I say that there can be a thought that may not have good consequences, I mean:
A thought that may cause you sadness…. or that may cause you stress or anxiety or which may spoil your mood…etc.

Do not let such thoughts linger, but dismiss them as soon as they appear. By doing so, you will get rid of them! Otherwise, you will regret it later!

Be aware of this as well: That the devil is lying even when he seems to be telling the truth!
Do you know that there is a demon of sadness? Sadness in a human sense does a lot of damage! It is like a worm eating away the tree and rotting it..

Ensure to always be smiling and cheerful! This helps a lot in the spiritual life! (The opposite is true of the opposite…)

I repeat: Once a (usually hidden) thought presents itself which conveys such unpleasant results, repel it at once! Not only you will not regret it, but you will enjoy it!

I wish you the best!
