Relating chakras to Maha Gayatri

While learning the Maha Gayatri last July, Kathy talked about how it relates to each of the seven chakras.

I thought about this again recently, and decided to take a look into chakras a little bit again, as a reminder, using the book Chakras: Energy Centers of Transformation by Harish Johari and relating them to the Gayatri. The gayatri addresses the ruling planes (lokas) of each chakra as follows.

Om Bhuh
- refers to the first chakra at the root (mul) of our spine, muladhara, which is responsible for the physical plane: Bhu Loka
Om Bhuvaha
- refers to the second chakra in the reproductive region, svadhishthana, which is responsible for the astral plane: Bhurvar Loka
Om Savaha
- refers to the third chakra at the navel region, manipura, which is responsible for the celestial plane: Sva Loka.
Om Mahaha
- refers to the fourth chakra at the heart, anahata, which is responsible for the plane of balance: Maha Loka.
Om Janaha
- refers to the fifth chakra at the throat, vishuddha, which is responsible for the human plane (where great spiritual darkness ends): Jana Loka.
Om Tapaha
- refers to the sixth chakra at the third eye, ajna, which is responsible for the plane of austerity or penance: Tapas Loka.
Om Satyam
- refers to the seventh chakra at the crown of the skull, sahasrara, which is responsible for the reality or truth plane: Satyam Loka.
