Rahu Kaal & Method to Calculate Rahu Kalam (Rahu Kaal)

In Indian Astrology, each day of the week has been assigned its respective

ruling planet viz. Monday is ruled by Moon, Tuesday by Mars etc. However,

Rahu and Ketu have not been given any specific day as they are treated as

nodes. However, Rahu and Ketu are given one and half hours time in a day

resulting three hours for Rahu and Ketu in which they can cast their malefic

influence since Rahu is a natural malefic.

Rahu Kalam (Rahu Kaal) is an inauspicious period of time for a particular day.

In other words, Rahu Kalam is the time during which Rahu seizes the

opportunity for influence. During this time one should avoid any auspicious

work like starting new business or project, buying expensive items,

investments, business transactions, journeys, meetings, interviews etc. It is

believed that any thing lost during Rahu Kalam is never found.

Rahu Kaal is one-eighth part of the difference between the Sunset and

Sunrise time of a particular place for a specific day of the week. The reason

for its 8th part is that in some Indian astrology systems, Rahu is considered

to be the 8th planet.

To calculate Rahu kalam or Rahu kaal, first find the local Sun-rise time and

sun-set time of the place. This can be found from a local panchang or your

local newspaper. Next divide the difference between the two time periods

into 8 equal parts. There is no Rahu Kalam during the first period of any

weekday. In other words, it is never just after sunrise. From Monday to

Sunday the period of Rahu Kaal or Rahu kalam for each week day is then

calculated as described below:

On Monday Rahukalam falls on the 2nd period

    Saturday                              3rd period

    Friday                                  4th period

    Wednesday                           5th period

    Thursday                              6th period

    Tuesday                               7th period

    Sunday                                 8th period

JANTAR MANTAR, The Astronomical Observatories of Maharaja Jai Singh II:

The Jantar Mantar Observatory was built by Maharaja Sawai Jai Singh II, as a focal point of his new capital, Jaipur, the first and earliest geometrically planned city in India. Jai Singh II was one of several powerful princes rising to power as the influence of the Mughal Empire decreased. In his attempt to become an almost independent ruler of Rajasthan, he started to build a new capital underlining the link between scientific capacities, urban planning and social control. The construction of the observatory site started in the 1720s and was completed in 1738.

Jantar Mantar is the most complete and best-preserved great observatory site built in the Ptolemaic tradition. This tradition developed from Classical Antiquity through to Medieval times, and from the Islamic period through to Persia and China. Jantar Mantar was greatly influenced by earlier great observatories inside central Asia, Persia and China.

The observatory was very active during the life of Jai Singh II, with around 20 permanent astronomers. After his death in 1743, this key landmark in the centre of the capital city of Rajasthan remained in use almost continuously until around 1800. This is evident from the fact that repairs were carried out at least twice during this period. Nevertheless, during the 19th century the site ceased to function permanently as an observatory, being re-opened from time to time between periods of low activity or complete abandonment. Some important restorations occurred at the end of the 19th century, and mainly in 1902, under British rule. This started a new life for the observatory as a monument of Rajasthan. Other campaigns of restoration occurred during the 20th century and the most recent took place in 2006–07.

The most significant instruments (yantras) among the collection are:

- Brihat Samrat, probably the largest gnomon-sundial ever built. With a gnomon arm 22.6m high and two lateral quadrants of radius 15.15m, it measures local time to an accuracy of 2 seconds.

- Sasthamsa, which has four large meridian dials inside two high black chambers.

- Jai Prakash, a highly innovative sundial made of two hemispherical bowls that produce an inverse image of the sky and allow the observer to move freely around inside to take readings.

- Great Ram is a rare, and perhaps unique, double-cylinder instrument to record the azimuth of celestial bodies;

- Raj comprises a bronze astrolabe 2.43m in diameter, probably the largest in the world.

- Kapala is able to record the co-ordinates of celestial bodies in both the azimuth-altitude and equatorial systems, and permits a direct visual transformation of the co-ordinates of any point in the sky between the two systems;

- Rasivalaya is a unique group of 12 gnomon-dials to measure the ecliptic co-ordinates of celestial objects, each becoming operative when a different one of the 12 zodiacal constellations straddles the meridian.

The Jantar Mantar of Jaipur was inscribed on the World Heritage List in July 2010. It is truly an "Architecture in the Service of Science".

Seva / Sewa - Selfless Service!

We define the terms "selfless "as that which is not performed primarily for ones own benefit and "work" analogous to "useful service" simply as any physical act resulting in gain. 

Though defined the grasp and depth of sewa is far more implicit. Naturally it leads to questions such as "Why?", "How?" and "To whom?" amongst many others. These are important questions that have been considered, debated and contested in depth. The answers have come from and have led to some of the most fundamental aspects of dharma.

Why Sewa?

The motives that inspire human beings to do an act of Sewa have been varied and many. The feelings of compassion, feeling of humanity, and sympathy are usually mentioned as reasons why human beings do Sewa. The cardinal principle is that God is residing in all beings human, animal, bird or plant. The same God who is present in me is also present in other beings. Therefore serving man and other beings is serving God.

To Whom?

As mentioned, this extends to all beings whether human, animal, birds, plants or any other. It also includes the environment and living in harmony with nature.

To What Extent?

This is a very difficult question. To what extent should a person give his time, efforts and wealth in charity? Is there a limit charity? All wealth is given by God and a person receiving or collecting it should not go on accumulating or hoarding it. To hoard more wealth than what a man needs is a sin. The wealth not needed by man should be given to others for use. One can amass wealth with hundreds of hands but distribute the same with thousands of hands.


Scriptures :

Paropakaraya Punyaya, Papaya Parapeedanam
"What ever conduces to the good of others is noble deed and should be followed"

Iswarah Sarva Bhutanam Itruddesha Arjuna Tishtati
"The same God who is present in me is also present in other human beings."

Shatahasta Samahara, Sahasrashasta Sankira
"Earn with hundreds of hands, and distribute with thousands."

Datavyamiti Yaddanam Deeyatenupa KarineDeshe Kale cha Patercha Taddanam Sattvikam Smarutam
"That gift which is made to one who can make no return, with the feeling that it is one's duty to give, and which is given at the right place and time and to a worthy person, that gift is held sattvik."
