Yes, true. How could you define good if there would be no evil. They both are not worth anything, its just what happens and how you interpret it. If someone steals some money of you, then offer him the same again... that kind of story is already quoted in the Bible and there is a reason for it... It will teach you not to be attached to things that can (and will be) lost.this suggests a complete symmetry between the "worth" of opposite sides of feelings and conduct
If you strive only for one side of the spectrum - only good deeds are acceptable - then you reject the opposite end and are attached to the positive end. This is attachment that leads to suffering as you won't be able to accept that also bad things happen... This doesn't mean that you should perform these bad deeds. Yes, once some attachments are relinquished you will seem to act loving and positive - but maybe also cruel and selfish as you don't really pity people as they would like to be pitied etc etc...
This is not true. Anger can be a very natural reaction to save your (or others) life. Anger is a form of energy that should not be suppressed, its only anger due to wrong attachment that is based on ignorance.How can anger be fine when any anger could be said to be due to ignorance
When this happens look at it and see. There will be no end to it if you don't drag into the light and let it run its course. Is this raging turmoil more than a barrage of thoughts happening?while at the same time an experience of local emotional turmoil is raging
