You got so far!
You got so far, so I guess you'll not be scared away by this next part. I know. Most people think of chakras and energies as spiritual bullshit. Woowoo nonesense. But for me, it was one of the most powerful teachings in yoga. The chakras were just a body-mind manual for this vehicle called body. Finally, everything I practiced made sense and I was able to attribute the different poses to my spiritual awakenings.
You have probably noticed that most of your inner experiences are echoed in your body. When you feel stressed, your stomach hurts. When you're in love, your heart is beating faster. Your sexual pleasure is perceived in your genital and pelvic area, not in your elbows.
