Nag Panchami :::
Why it is Panchami ?? and not Astami ???
As i understand, Nag is the coiled snake lying dormant in us - Kundalini(coiling like a snake)
we have to raise our kundalini with our Sadhna.--"pranic awakening"
once kundalini is raised we outgrow Panch Maha bhoota(Panchmi) and merge with Shiva .. enjoying the sweetness of His bliss (laddus offered to Naga)
We even offer Panch-Amrut to Naga - Panch Tattwa's
I feel Nag Panchmi signifies raising of the Kundalini, outgrowing the Panch Maha bhoota's and reaching HIM ...
