The idea of rising of Kundalini energy through the six chakras

The idea of rising of Kundalini energy through the six chakras and finally reaching the sahasrara and up -- even without seriously believing that such phenomenon is a reality--can give an idea as to what we have to jettison and move up..

As we move upward from mooladhara, swadhishatan, manipoora, anaahata, vishuddhi, and ajna chakras...in that order, if we are to reach the yogic samadhi of no return, we just forget each stage below. and move up.. and in that process, even the lower chakras themselves become redundant and at those stages we have to completely abandon them.. otherwise one cannot really move up..

Gita talks of "VishayaaH vinivarthante niraaharasy dehinaH..विषयाः विनिवर्तन्ते निराहारस्य देहिनः".

desire for worldly this get repelled away from a person who consciously starves the body of such desire--

these are all indicators..

But some can easily jettison the fluff, some will have to starve and burn off calories, some others require surgical intervention, and some succumb to the fatty content.. Each has his own way....
