Is it the sense of freedom? Is it the pleasure of the wind rushing through your hair? Is it the motion recalling the womb time? Is it the feeling of letting go, succumbing to nature's flow?
Whatever it is, it brings a suspension of whatever troubles you. Perhaps it is just back and forth, but it feels free, it feels like a reprieve. When no answer comes, no solution, when you feel stuck, sometmes you just need to swing.
