If anger or frustration is a factor in your life, you have simply separated from oneness by using “I, mine, me“. You have forgotten that nothing is beyond the mind. You reject what occurs in the moment. This is the source of your anger. It is the source of your frustration.
You can never push the reality aside, because it is the fact of the present moment. Remind yourself, “I have created this situation.” Surrender your ego, and accept the reality. Set aside your anger, doubt, conceit and bias. These are part of your ego, so they will continually generate negativity unless you control them.
