Ya know, I have been meditating for 4 decades (and have fabulous experiences,
no more struggles)...and do all of what you said
....focus inward, outward....whatever....I do
focus on my breath, well, not exactly, but
what 'powers' the breathe, what is behind the breath...the Thing
that is breathing me.
I also, do not do mantras....Why? They end...I say focus on that which does NOT
have an ending or a beginning, Ha!
There is a Divine Presence....open to That!
I'm inspiring mySELF, now. Ha!
