Doubt: A Poison, A Thorn & A Sword

There is nothing more dreadful than the habit of doubt. Doubt separates people. It is a poison that disintegrates friendships and breaks up pleasant relations. It is a thorn that irritates and hurts; it is a sword that kills.
Buddha quote

Ouch!

We can complain because rose bushes have thorns,
or rejoice because thorn bushes have roses.

Abraham Lincoln
