Ostaristic 

A visually induced sensation that leads to soul pacification.

Through your mind’s eye your heart feels safely understood and alive. (Can manifest into wistful flashbacks, summoning narcissistic rapture and creativity).

That’s quite an Ostaristic painting; it really struck a chord.
I just feel Ostaristic about it, so leave it alone.
A tall strider named Ostaristic also known as Mazzranache.
