It occurs to me to add as well that I experience “new emotions” regularly in my practice. Part of it is asking for them, but much of it is simply avoiding labeling what comes up.
And if you think about it, if you do not like the feelings that occur daily for you, to change them you need new ones, more open ones, more empowering ones, and how could they not feel foreign at first?
There is metainformation in ANY new feeling, negative or positive: what it tells you is that something different is possible. The sense of the possibility of change is necessary to ever consciously embrace change. And I think if it is not sought, some part of our unconscious snaps us back to the same spot regularly. It brings us back to “who we are”.
