It is all chemistry which is a science pure and simple .. only if we understand profoundly .There are reactants ..products and catalysts ..hypothesis is all sins are cringed to the soul in physical form ..donot ask me weather the soul is physical or not ..you are not following is the inference. they carry us to the lower pane or higher pane of universe ..and can be dropped with the help of a long thought process which is other wise understood as Tapasya or some time with the help of catalysts of a positive energy sources ..Sankara mentioned the concept as Satsangatve nitsangatvam in this context perhapes .
The day is not far where the purity of physical form will be attained by mere adjustment of energies when entire world will be blissful and tranquil .. the real epiphany of socialism and true devine land concept contemplation is in the offing ..
with lot of efforts on the natural flair state of blissful minds ,mitsery or agony are implanted ..cultivated .. drugs give a temp phase of bliss but a long drawn thought process makes it stable .
All upanishats are more or less telling this but discarding of concept and following rituals making things worse.. even that phase too passes over a period ..other words the earth too has a horachart and will have different phases that offer to the inhabitants .. nithya narthanam is only the constant one ..
