What place does anger have in spiritual enlightenment?

[Jo96]

I keep reading all these “spirtual pages” usually on meditation;Talking about how we should not reject  or accept a thought or emotion. That is in essence meditation. So then why is anger and jealousy something which is seemingly rejected in spirituality. Why would bliss or happiness be more important then anger or sadness?

Well first you need to ask yourself. What is anger? What is jealousy? Imagine someone just slapped you in the face now you're angry now ask yourself what is anger. NOW GET REALLY HONEST. I'm sure you would agree you're actually hurt someone just slapped you in the face and now your emotional hurting. So now what do you do with that Well you get angry of course but if you're really honest you can just be hurt and vulnerable and from that honest vulnerable place you can handle the situation better. Or you can just be angry ?

Jealousy is sinful, anger may or may not be.

Hatred is sinful, indignance is not.
