On the vibrational level, fire as overseer of the 7 passions/motivating forces or chakras does well to give the Cosmos form. Vibration on its own is an even sea of energy filled with many constituent vibrations of ego. Fire stirs this grey sea of energy into something with form and purpose. The Fire gives us sexual energy on the simplest level. This sexual fire unifies that which has seperated from source and reminds it that it is one with each other and can come again together if it is willed; this type of mentality is located on the base chakra of humans. The other chakras do just as well showing diffferent aspects of the Fire.
