The Rationale behind Rahu Kalam

The Rationale behind Rahu Kalam 

This article is purely based on a very ancient Hindu belief system. It is not backed by Empirical evidence Or Scientific Analysis.

 

The Rahu in Rahukalam does not refer to the shadow planets Rahu and Ketu of Hindu astrology, it refers to the colors of a group of sun-rays :

As we all know, "vibgyor"  represents the seven colours of rainbow. If we reverse it, we get "roygbiv", namely red, orange yellow, green, blue, indigo and violet. After violet, there is another group of rays called "ultraviolet"  rays which are not visible to naked eyes. If we divide the daytime of Sunday into 8  parts of 1.5 hours each, this will be the order in which the coloured rays will occour. In subsequent days, the starting colour will be different but the sequence will be the same.

 

The following table will clarify things properly:

Time	Sunday	Monday	Tuesday	Wednesday	Thursday	Friday	Saturday
06.00-07.30 AM	Red	Violet	Orange	Green	Yellow	Blue	Indigo
07.30-9.00 AM	Orange	UltraViolet	Yellow	Blue	Green	Indigo	Violet
09.00-10.30 AM	Yellow	Red	Green	Indigo	Blue	Violet	UltraViolet
10.30-12.00	Green	Orange	Blue	Violet	Indigo	Ultraviolet	Red
12.00-01.30 PM	Blue	Yellow	Indigo	Ultraviolet	Violet	Red	Orange
01.30-03.00 PM	Indigo	Green	Violet	Red	Ultraviolet	Orange	Yellow
03.00-04.30 PM	Violet	Blue	Ultraviolet	Orange	Red	Yellow	Green
04.30-06.00 PM	UltraViolet	Indigo	Red	Yellow	Orange	Green	Blue

 
Ancient Tamil Hindus named the period of "Ultraviolet" rays as "RAHU KALAM".

Semi Rational people like most of us need not get scared by RAHU KALAM. As far as possible, they may remain at home or office and indulge in ethical deeds.  If at all, it is essential to travel during this period, they may chant Rahu Kala Durga Ashtakam or Durgasaptha slokee. Idea is not to get exposed to the ultraviolet rays being emitted at that time. Tuesday Rahukalam is taken more seriously as mars is linked with blood or accidents. Pujas during Rahukalam are ideal.

 

The sequence of colours of rays at night is exactly reverse of the sequence  in the day,  as we see in a mirror.  So, there is Rahu Kalam at night also.  Nobody Takes it Seriously as most of us are asleep during that period. 

 

Let us travel the middle path between reason and faith.
