The flame has seven licking tongues, Kali, the dark one (Muladhara), the terrible (Svadhishthana), the swift-as-thought (Manipura), the crimson one (Anahata), the smoky colored (Vishuddha), the sparkling one (Ajna), and the Devi (Sahasrara), she who takes all forms."
"Whoever performs the sacrifice (raises the serpent fire) correctly, when these seven are enlivened, he is led by them, as the rays of the sun, to the world of the lord of the Gods." Mudaka Upanishad Shearer/Russell (Parenthesis added by poster) "From him have sprung the seven gates of sense;........ and the seven subtle centers shining in the body"
