I drank coffee before practicing Kundalini.
We know that coffee stimulates our bodies.
During the 50 minutes that I practiced Kundalini Yoga, side effects did not appear. It was not until the moment of meditation, where I closed my eyes, covered up myself with a blanket to keep me warm, and left the lights on.
In front of me was a mirror, I began to see myself sleeping, till my sight started to become distorted, my pupils changed size; from big and profound till a small scale moving like water's waves and savage winds. Around me everything started to have movement with same perspective.
