A part of embracing the flow of allowance is allowing anything that is in resistance to the flow to be released. This is to stop obsessing over it, or feeding it through the fear that it is going to happen again; instead, it is to allow its release by understanding that as any wound is healed, the emotions contained within it will pass through your awareness and be felt.
Being in the flow of allowance long enough will eventually lead any area of resistance to open, be explored and released. However, an overt focus on “only focus on the positive” can act as a brake, as you will avoid the negative sensations that naturally arise when the flow of allowance brings your wounds forward for healing / transformation.
