The period of Sade-sati starts when Saturn enters the zodiac sign immediately be fore the zodiac sign of Moon at the time of the birth of the individual. That is , if the Moon sign (Ayamsha) at the time of birth of the native was Taurus, then the Sadesati will begin when Saturn enters sign Aries. The Sadesati will contin ue while Saturn transits over this sign and the next two signs, i.e. the birth s ign and the sign after it. Saturn spends around 2½ years in each sign. To cross th ese three signs it takes about 7½ years. Thus the name Sadesati which literally me ans seven and a half. According to one school of Vedic astrology this is a troublesome time for the in dividual who is going through it. There may be a lot of challenges in a person's life, and he may face accidents, sudden failures, money and health problems. Ho wever, there's another school of astrology that believes that though the sadesat i period is challenging, it is not as damaging as many astrologers claim, and th at many people actually achieve a lot of success during the period of Sadesati. Sadesati is development of the brain its a learning curve. The impact of Sadesati is supposed to be felt differently by people of different moon signs. It is said that people of Moon sign Aquarius do not have any ill ef fects from Sadesati, while people of Moon sign Leo feel the most impact. Vedic astrology also prescribes certain remedies and mantras that can be recited to please the lord Saturn and limit the effect of Saturn's Sadesati. Another related astrological transit of Saturn is the Dhaiyya (2.5 years), also known as Small Panoti (Small Trouble), and Kantakshani, or Ashtamshani. This tra nsit of Saturn occurs when the Saturn is transiting through the 4th sign from th e birth Moon sign (Kantak Shani), or from the 8th sign from the birth moon sign (Ashtamshani). Vedic astrology says that these two are hazardous periods, though not as much as the Sade-sati. But if there is a proper system then this period of sadisati will not effect any human being. Chanting the hanuman chalisa is a verry good remedy to sade sati.
