After an unusually strong and long focus on the sensation of my body i felt that the sensations were growing stronger and stronger with time as i focused, and then i felt like if my nervous system was extending beyond my body to the nature outside. I was in the woods. And a feeling was like if i was feeling all the nature around me like a part of my body.
It is now a year into my practices (i do different ones, also tried AYP, doing daily). I feel that this is a sign that i'm on a correct way.
