¡Hi, all..!

A very useful meditation routine is TUMMO Meditation. Its practitioners are able of to sit naked onto ice blocks, melt them and even dry wet bed covers placed over their shoulders.

This is a solution for Earth sites where weather conditions makes life hard done low temperatures.

Pd.:
And a solution for certain countries where its government prosecutes hard tax policies related to natural gas supply, like at Argentina (at southern end of America Continent), with increments nearing 2000%. Unfortunately, meditation is away from its educational programs.
