Thoughts.
For million of years before they reach any object.
Similarly thought waves may also travel,
Hundreds of years before they meet an object.
So our atmosphere is full of such thought pulsation,
Both good and evil, projected from every brain goes on pulsation.
Mind which is open to receive,
Some of these impulses.
Will take them immediately,
And create certain state of tensions.
So an evil doer generally,
Goes on doing more and more evil.
His actions become intensified,
Such may also happen with good doer as well as evil.
We open ourselves to all the evil influences,
And we create evil which affects others.
