Rahu-Ketu The nodes of infinity

Ohm Gam Ganpatye Namah:!
I am offering this post to Lord GANESHA as a humble offering .I am only a mortal human being blessed by him to be able to add few drops to vast ocean.I am subject to all doshas and he is the one who shows the way.

The body of humans conatin Rahu at Muladharchakra(The nervous perplex in the lower part of abdominal region ) and Ketu at SHASTRADHAR (the nervous perplex at the apex of head).The whole body is powered between two node Rahu and Ketu.
The astrology also talks of two nodes Rahu and Ketu and the predictions also range between positions of two.
Adiguru Shankracharya said every thing comes from infinity and goes to infinity .Rahu and Ketu respresent the entry and exit of infinity . They cannot be measurable but they effect everything.
Lord Ganesha the headless god with head of elephant so the upper part is rahu and the lower part whcih is not having own head us ketu. The vighnharta prathampujya himself is the having the infinite nodes that is why he is worshiped first before any ritual.
Why they are so dreaded in Jyotish?
There is nothing to be feared about.Rahu represnts the head that is gyan and ketu represent the selfego,self consciousness of body. When on other end their placement has resulted in yogi like Shri Ramkrishna Paramhansa and at the other end person like Hitler.So what happens when ego combines with gyan it reults in aham (self ego) of false assumption that i am omipresent and ominipotent which leads to destruction whereas when gyan combines with selfconsciuosness it goes beyond medha (intellignece )and become pragya (the supreme knowledge of self).We the ordinary mortal fall in between so are torn apart by illusions.The illusion of self , the illusion of money ,the illusion of lust ,the illusion of power so we are the sufferers ..
