Why should a sadhak never curse anyone?

Question - Gurudev, why should a sadhak never curse anyone?

Gurudev Sri Sri - Whatever work we want to do, do it with good intentions. Nobody’s curse can affect you if your heart is pure. If your heart is impure then surely it will have an influence. Do not blame the world or curse the people around you. They are all a part of God’s wonderful creation. Everything here has a purpose, and everything here is to make you stronger - be it, friends or enemies. When people don't live up to your expectations, you get frustrated and you blame or curse them. By cursing, you lose your spiritual energy. When you bless, your energy goes up. Your own experience tells you time and time again that expectations reduce your enjoyment of life. Yet, most of us do not even realise, having too many expectations about everything, could be a reason for not being naturally happy. By cursing, you lose your spiritual energy. When you can bless, your energy goes up. When you are full, the need to give curse never arises, it may happen in those who feel some lack. Speech is a big power. Our words are there to bless people, bring peace in the world never curse. Weigh your words before you speak them out. They are pearls of your life. Don’t lose them for nothing. Do not blame the world or curse the people around you. They are all a part of God’s wonderful creation. Everything here has a purpose, and everything here is to make you stronger - be it, friends or enemies.
