Even though you may experience some peace when you sit in meditation, don’t be in a hurry to congratulate yourself. Likewise, if there is some confusion, don’t blame yourself.
If things seem to be good, don’t delight in them, and if they’re not good don’t be averse to them. Just look at it all; look at what you have. Just look, don’t bother judging.
If it’s good, don’t hold fast to it; if it’s bad, don’t cling to it. Good and bad can both bite, so don’t hold fast to them.
