How do you navigate being separate and non separate simultaneously?

For my witness folks, my disassociating folks, my ram dass/spiritual/existential folks.

Sometimes I vibe with it. Sometimes I welcome it. Sometimes I feel so uncomfortable I feel a large anxiety attack based on inevitability just absorb me.

This is when I realize this is all phenomena. So I see both. I manage it well externally but would appreciate some tips for managing it internally. What a trip.
