I somewhat familiar with the movement of prana in my body. I have been practicing yoga and meditation for eight years, more unregularly the last four and a half years since my first child was born. Recently in centering before physical yoga practice I felt energy move and coalesce at the base of my spine and move upward and out the crown of my head. It was brief and the ray of energy was about the width of my spinal column as it moved up.
I have read that kundalini is more than just a physical/energetic experience. Perhaps more importantly a psychological unfoldment, when the ties of conditioning and ego are loosed and we begin to glimpse our true selves.
This has not been a permanent experience or true merger, but can I understand that in that moment because conditions were right in mind and body, this rising was experienced? I have also been studying the first chapter of Patanjali’s Yoga Sutras.
