This is why we are all attracted to this art form.
We are all born with the ability to breathe, move, empathize and have compassion for all things. We use yoga to get into the body. We align our limbs to express a specific posture. AND this posture brings our life force (breath) into our organs. This is nourishment for the soul.
We have to break through the physical form of asana to reach the moment when we are lucky enough to engage the spirit within. This higher self, the humming that occurs out of nowhere, the words and thoughts that just pop up, the visualizations that give you inspiration and make you happy. This you is universal, elemental and variable. You are connected energetically to all the people around you and also all the non-beings, ie. rocks and plants that surround you.
You are forever shifting from that which you think of and put energy into.
All we need is all we have: the silent rhythm of our breath, and the connection to our physical sensations to sustain us.
