Gochara or transit is a topic which has been viewed from various standpoints in astrological classics .The most commonly followed technique of delineating Gochara results is based on transit of slow moving planets Saturn Jupiter Rahu and ketu in relation to the natal Moon   
Asrological classics such as Deva Keralam Brihat parasara Horasastra jataka parijata Hora Ratnam prasna Marg jataka desh marga and others speak of certain sensitive areas in a birth chart and transit over these areas by Saturn is said to cause much distress and even death One such sensitive area is the 64th Navamsa (3°-20׳ or 200 minutes of arc ) from the Navamsa occupied by the Moon or the ascendant The represen tation is the result of the author s research in the virgin area which has remained largely unexplored The author wishes to discuss certain aspects of the mysterious 64thNavamsa The 64th Navamsa is nothing but 210th degree i e the 8th house aspect (dexter quincunx aspect according to Western Astrology )
The 64th Navamsa from that occupied by a planet will be the same Navamsa in the 8th sign in order of sequence For instance a planet is in Mesha 8-30 in the 3rd Navamsa from the beginning of sign Mesha the 64th Navamsa will be the 3rd Navamsa in Vrishchika the 8th sign The 64th Navamsa will have the asme degreecal Navamsa arc i e in the above ex ample the Navamsa of the planet ranges from Mesha 6-40 to 10- 00 and the 64th Navamsa will range in Vrishchika from 6-40- to 10 -00 and 64 divided by 12 will leave balance 4 so the 64th Navamsa sign will be the 4th sign from the planet s Navamsa sign i e in the above example the said planet is in Mithuna Navamsa of Mesha sign so the 64th Navamsa sign will be Kanya in Vrishchika sign
The concept of the 64th Navamsa has been developed by dif ferent authors from various standpoints For instance jataka parijata reckons it from the Moon while Brihat parasara Horas
astra reckons if from the Moon and from the ascendant while prasns Marga reckons it from the Moon the ascendant and the Sun also
