Here's an interesting thought from "A Gift From The Stars" by Elena Danaan - in some ways it's a supplementary to my previous post (I considered making it a PS there, but want that one to stand on its own);
"Do not look for portals: Be a portal. Instead of trying to find geographical places where you can shift dimensions towards other realms and times, remember, you are the tree, you are the ladder, you are the door. Planet Terra has its own portals and vortexes, some are fixed some are not, but any living being who has ascended to their own capacities, can open doors too. Become the key. The door is within. Always."
