I place Entropy on the floor next to me before meditating, I feel the space around me feeling the shifting of Entropy next to me, I start moving a small piece of wood and cast a float spell on the piece of wood letting it stay in the air while I feel the space shift, I've been training my ability to feel space by doing this, it's probably not the best way to go about it but I don't know a better way and I don't think anypony else would know a better one, I stay like this for some time before standing up.
