Once we experience 5D and higher, getting hit with 3D "reality" is rough, but better than before becoming "aware". Now we see things with a whole new perspective, with a purpose, and nothing personal. We learn to appreciate the experience and opportunity to learn & help others heal while healing ourselves.
But, physically, in the 3D world, no matter how much we have learned and understand, dealing with it can take its toll on on emotionally & physically.
One of the "best" things, is that since we can "see" things differently, have released many attachments, overcome the obstacles thus far, we can "shift" much easier & quicker than before. Before, there was a time that we didn't have this "ability", because we were still "asleep" in our "remembering". Now we flow with the 3D experience (if we are lucky), instead of creating additional blocks, and clear/move through them quicker hopefully without as much 3D emotional pain as before.
We consciously take responsibility for the experience, own it, use it to learn from and heal and work to clear it from our energetic field. Until we do, it lowers our vibration.
There are no highs without lows. It is all part of the duality. The pain causes our heart to open. That pain provides an opportunity for healing. Embracing it and not getting stuck in it is another part of it all.
The difference now is how we "handle" the lows, respond and grow through them instead of becoming victimized by them. Then, we can in turn help another, when they are ready, to help gain the tools and awareness to heal themselves.
I get the multi-purposes in things now. My healing is for me, which also heals another, as we are one. So healing for all. It is truly amazing to know and see such a thing. That alone helps create compassion, love and appreciation for the experience alone.
