Sade Saathi has many names such as Sade Saathi, Shanichari, Musibathi, Aafath etc. Nature is well understood by the science of astrology. Astrology has many branches such as Vedic Astrology, Industrial astrology, personal astrology etc. In these branches of astrology, the study of Rasi and the effect of planets have an important place. In the science of astrology, all the aspects of life are affected by the combination of planets in a group. Every planet is attributed with a special role. Happiness and sorrow play hide and seek in man's life. In some people's lives there is more happiness as there is more unhappiness in some people's lives. The attaining of 'moksha' is the ultimate goal of man's life.
In the astro-charts of many astrological texts planet Shani has been given the place of the planet of sorrow. This may be true only up to an extent and in certain aspects. It is shown that God Shani, soon after his birth, showed a glimpse of his nature to his father God Surya. God Shani, who symbolizes righteousness and justice, creates Sade Saathi. Sade Saathi is a period of 7 and ½ years. Shani takes 30 years to traverse all the 12 planets. He stays 2 and ½ years in one 'rasi' or sun sign. When the planet, aspects the lord of the house, then the good benefits are derived. In the garland of planets, God Shani is called 'Chaya Martand'. When 'Chaya Grah' or the star passes through a house, that star sign's previous star's sign and the next star sign is troubled. That is 'Chaya Grah'. This belief is accepted in Sade Saathi. When Shani passes through the 12th house of the birth chart for the second time, then it is called as Sade Saathi. Shani stays in a house for 2 and ½ years. This way, God Shani's transit through 3 houses is called Sade Saathi. (2 and ½ x 3= 7and ½). Therefore, this patch of 7and1/2 years is known to bring suffering, sorrows and misfortune. This is known by people as Sade Saathi.
In the birth chart of Moon sign, when there is Shani behind and ahead, till then it is called Sade Saathi. In the normal course, the effects of Sade Saathi are common to all creatures. Then, whether they are saints, commoners, great people, spiritualists, Gods or godly people, all have them have the same effect on them. Whether it is King Veer Vikramaditya or Nala Damayanti or people of all kinds, the effect of it is the same on all.
Whichever Rasi has Sade Saathi, on that day's previous Rasi when Shani is upon it then it is called Ascendant Sade Saathi. Ascendant Sade Saathi for some in the middle and for some in the end as Decscendant Sade Saathi is favourable. Any big solution sought for Sani in Sade Saathi, takes a small shape. And when the time comes for the benefit, it comes in a big way like a miracle. As per astrology, Shani's Sade Saathi is understood in three parts. One is from Lagna, the other is from Moon and the third is from Sun. Over a period of thirty years, every chart is affected by Sade Saathi once, whether he is a lion or a king. Sade Saathi touches every birth chart. The Moon's aspected Sade Saathi is accepted in north India. In the chart, where the moon is seen one house before and one house after, till then there will be the effect of Shani. For example, till Aries and Taurus , there will be the effect of Sade Saathi.
In Sade Saathi,a great deal of misery, trouble, fearsome disease, excess sorrow, loss of money, blame, insult, illness, imprisonment etc are undergone. By taking the help of 'Vedic Vidhi' and the mantras, penance etc the fearful effects of Sade Saathi can be reduced. In brief, Sade Saathi or seven and half years of God Shani put the normal life of man into great distress. This is the direct result of Sade Saathi that normal, ongoing work comes to a stand still. The desire of students to study goes away. And people who are looking for a job go further on and on in this quest. In the birth chart, if Shani is exalted, powerfully placed then the Sade Saathi will be that much more pronounced. Which means, there will be a great loss of wealth.
The effect of Sade Saathi will be on Aquarius, Capricorn and Pisces in the Lagna Rasi or it will weaken the strength of the Rasi. Which means, it will reduce finance and success. Shani's Sade Saathi troubled many brave and strong kings, but they never let go of truth. Sade Saathi gave them too much trouble but it could destroy them. Raja Harishchandra did not abandon truth till the end. Only then, God Shani was pleased, restored him to the throne and gave him progeny, wealth and made him pure again. He gave him the strength to do penance.
When one is affected by Sade Saathi, one should make use of prayer as a boatman and cross the river of bad times. One should resort to falsehood, theft. Robbery, vices, bad habits etc in one's life. One should remember that thee is no role of God Shani in Sade Saathi. He cleanses us of the sins of our previous births and brings us closer to the divinity of Ishwar. During the period of Sade Saathi, if we take the help of our own prayers, penance and 'mantras' and hold on to truth, then it will have been worth it.
