Revenge gives temporary satisfaction, but recurring enemity and long time regret and guilt. To take revenge is normal, but to forgive is divine. It takes an extraordinary mind infused with maturity and wisdom to forgive.
When revenge is swirling in the mind, we feel agitated, restless, aggressive, scheming and fuming. Life of the self and those around will remain miserable.
When forgiveness lingers in the mind, it cools the mind, bring peace and a sense of divinity in us. It breaks enimity, infuses a great relief in all.
