The best way to determine which chakra to unblock first is to identify which chakra is most out of balance. To do this, you can use a chakra test or energy healing session to help you identify which chakras are blocked and which need the most attention. Once you have determined which chakra needs the most attention, you can then focus on unblocking it. Common techniques for unblocking chakras include meditation, yoga, sound healing, affirmations, and journaling.
