You will not become tasteless, you will have an enrichment to your taste. You need a little salt. And anger is exactly in the same amount as it is needed. When it overpowers you, then it becomes ugly. If you eat only salt then you will die.
Salt has a proportion, and in the proportion it is needed, absolutely needed.
On the path you will meet many people who would like to cripple you, to cut you, to dissect you. Anger is bad, hate is bad, sex is bad. They will go on cutting you, and by the time they have left you, you are simply paralyzed, a crippled one. You have no life left. That's how the whole civilization has become paralyzed and crippled.
