The energy for the creation of each of these chakras came to me in this order from first to twelfth. This has no implications for how you might use them. In my process each one was an attunement and seemed to clear the way for the next one in this order.
"Connected to the pineal gland, cerebral cortex, and our higher chakras, this chakra regulates many in- and out-of-body functions...The 'psychic center' for higher knowing, it receives the spiritual energies and guidance necessary to activate our purpose. Because it is connected to higher planes, the seventh chakra is seen as the center of our divinity, the place through which we know our unity with the Divine Source and all other spiritual beings."
