Instead when it happens, afterwards, regress into the situation. What were you attached to? What outcome did you think needed or couldn't accept? Work to let go of this attachment, yes. But keep brining awareness to the pattern as it is happening. Work to open a space through the trigger in the light of your awareness. Soften the space or the reaction as you're in it. You come into infinite potential where time slows right down.Now look for the authentic expression that wants to come through instead - a sense of beingness. Where it might previously have been anger and frustration, maybe it could now be willful, but without the extra energy? Maybe you could get your point across, but also with humour?
Getting triggered is something we'd probably all prefer to avoid - where your buttons get pushed in a particular situation and you react. It doesn't always look pleasant! No wonder there's a spiritual desire to surpress and push away.
However, this is highly likely to be counterproductive and derailing, because you end up supressing an authentic expression of the soul that is buried in the trigger too. You risk throwing the baby out with the bath water.
In so doing, the triggers naturally dissolve and authentic soul expression comes through.
