Wow, that's crazy to be questioned on a spiritually minded site. There are dogmatic people everywhere I guess. Sorry you got shut down like that. Sucks your dad would do that to you as well with your feelings.
I get the vibe that people on this forum aren't super happy about talking about spiritual things but I don't mind. I think body mind and spirit are all connected.
I think it is foolish to ignore a spiritual realm. Even if you start with simple vibrations and keep your mind open you can move up into harmonizing with nature, etc. There are no limits!
