Guest guest Posted September 6, 2008 Report Share Posted September 6, 2008 Namaste friends, As I mentioned before, I have experimented with a variation of Lahiri ayanamsa that uses a fixed zodiacal plane. Normally, people use the Sun-earth plane as the zodiacal plane and it has a wobbling motion. In other words, longitudes at different times are measured on a different plane, as the plane wobbles with time. When we are fixing the starting point of the zodiac, does it make sense to have a plane that is not fixed?? The entire solar system has a rotation too (around a point that we refer to as " Vishnunabhi " - navel of Vishnu). The equatorial plane of this rotation is very stable and has no wobbling motion. It makes excellent sense to use this plane as the zodiacal plane instead of a wobbling Sun-earth plane. When I used this fixed plane instead of wobbing Sun-earth plane, the longitudes of planets change by a few arc-sec and sometimes by a few arc-min. However, unlike in regular ayanamsa changes, the change in different planets is different. Thus, (Moon-Sun) differential changes differently at different times. This means that times of Tithi Pravesha (Sun-Moon angular return) can change by several minutes compared to regular Lahiri ayanamsa. This changes the lagna in several divisional charts of TP in almost all years. I compared the divisional charts of TP between the two ayanamsas and concluded that the fixed plane version is more consistent. I use that ayanamsa myself. * * * However, one thing still troubled me. Though the choice of the plane is very logical and not really arbitrary, the choice of the zero point has a little arbitrariness. I mean, Chitra at 180 deg is logical. But we were taking Chitra at 180 deg on a particular date. That is arbitrary. At later dates, Chitra may be slightly away from 180 deg due to the slow star motion. It is possible to define the ayanamsa such that Chitra is at 180 deg at all times, i.e. slow motion of star is factored in. This causes only a few arc-seconds of difference in the longitudes and it affects all planets uniformly. Hence it has no impact on TP times (Moon-Sun does not change as both Moon and Sun change by the same amount). It cause changes in divisional charts only in border cases that are anyway susceptible to very minor birthtime errors. Thus, this difference is mostly of academic interest and the practical implication is very little. On the other hand, the practical implication of the previously mentioned use of solar system rotation plane (already available in JHora 7.2) is huge. It changes all TP charts (not just border cases). Nevertheless, I think the arbitrariness should go. Fixing ayanamsa based on a specific date is arbitrary. Thus, I have modified the ayanamsa to place Chitra (Spica) star at exactly 180 deg always. The starting point of the zodiac is fixed in such a way that Chitra star is always at 180 deg exactly and the plane of the zodiacal plane is fixed to the solar system rotation plane around Vishnunabhi. In my mind, this is very logical, consistent and not arbitrary. Neither the plane nor the starting point has any silliness built in. When I made this change in the ayanamsa I am using, I see no impact on TP charts and all my previous analysis still holds. However, to be more logical and remove arbitrariness from my work, I have switched to this ayanamsa. I made my final decision. I will make it available in the next JHora release. For the benefit of those who dislike the fixed Vishnunabhi plane (why???? why use a fixed starting point when the plane itself is not fixed?????) and want to stick to the regular wobbly Sun-earth plane, I will add another various of Lahiri ayanamsa. This will also place Chitra at 180 deg always, but on a wobbling plane instead of the fixed Vishnunabhi plane. I will make this release by the end of September. I hope that the serious researchers of astrology will take advantage of this. * * * Mooladhara chakra represents bhu loka - the earthly realm of consciousness. Other chakras represent higher lokas - the higher spiritual realms of consciousness. While the 0 deg of Aries contains the head of kala purusha, i.e. sahasrara chakra, it is the 180 deg point that contains mooladhara chakra. The top seven and bottom seven chakras/lokas are in the two halves of the zodiac. From this point of view, it is very logical to base the zodiac from 180 deg point, i.e. Mooladhara chakra. While the people who fixed Lahiri ayanamsa got it mostly, things like factoring in the star motion and fixing the zodiacal plane were left out.

Guest guest Posted September 7, 2008 Report Share Posted September 7, 2008 Dear Sanjay and Narasimha, I trust your opinion, particularly in matters that, due to my knowledge/interests/life style limitations, I cannot fully understand. I've always believed, though, that we all are blessed by being granted guidance, limitless source, for every path which God has offered us. From 'Sourceres' like yourself. Perhaps, I share this with many students, as well as /ever-growing/ appreciation of sharing your knowledge, research results, opinions, suggestions, examples, predictions- that's 'hands on' study experience, superior to any other study method, indeed! Thank you very much for giving such a good quality food for our thoughts, growth and mastering understanding of Jyotish principles and prediction methods. Please continue to share your knowledge and research results as much as you can. This is supposed to be my way of thanking you and inviting more information, comments from you. As 'a piece of divine force' myself, I do expect that, LOL. Love, Anna Quote Link to comment Share on other sites More sharing options...
Guest guest Posted October 11, 2008 Report Share Posted October 11, 2008 Dear Narasimha, I hope you are well... With regards to the new ayanamsa in JHora you stated: " I will make this release by the end of September. I hope that the seriousresearchers of astrology will take advantage of this. " I wonder if you have been able to do this?? Also when will your book on TP come out? Or has it already come out??

Guest guest Posted October 11, 2008 Report Share Posted October 11, 2008 Namaste Kasim, JHora: A couple of requests came for a couple of interesting new calculations and I wanted to add them. So it is postponed. Probably by the end of this month. TP Book: I restarted it and want to finish it soon. But I cannot give any dates.
