Kundalini yoga practice generates a lot of energy, which can be expressed in an infinite number of ways. As long as you are approaching your practice with an open heart and mind, nothing that you’re experiencing is strange or unusual, or an indication that you’re doing the practice “wrong.”
It’s important to understand that a Kundalini yoga practice, or any effective yoga practice, will bring a lot of subconscious patterning into your awareness. This often makes people believe that the practice isn’t working, or they’re regressing in their development. In fact the opposite is true: this is almost always an indication that the practice is working and you’re exactly on track.
