Very good information shared. Although I consider myself as a toddler in astrology and follow lagan chart only not much into cuspal charts or nadi astrology, So in respect to lagan chart should we also consider 6th house as the past life karma? Learned members can validate on this. If we see planets in 6th house from ascendant, Planets sitting in 6th house, 6th sign lord and its connection and siginfication.
Another note is to count x numbers of sign from your ascendant.
X= number of your ascendant in kapurush kundali/ Natural sign number ( Aries- 1st house, Taurus -2nd, Cancer-4th)
So Let's say if you are a Libra ascendant, Libra is 7th natural zodiac sign. Count 7 houses from Libra. It will be Aries. Check Lord of Aries(Mars) Where it is sitting and its nakshatra/significations.
That's most probably you are here to learn in this life time.
Let's take an easy example. If X has cancer ascendant. Which is 4th natural zodiacal sign. 4th from cancer will fall under libra and we need to see where Venus(Lord of Libra sign) is sitting. Let's say its sitting in 7th house Capricorn. So 7th house is about marriage, legal partnerships and venus is related to women/luxury/relationships. So we can calculate X is here to prominently learn about these significations , Further we can also calculate nakshtara and dignity of venus to know further.
It's just a raw info , Needs to check/validate from learned members.
For Saturn, Rahu, Ketu. You are on point, Phemanth. We are here because of Moon, Rahu and Ketu are nodes+ Karma comes from mind, thoughts, Ketu that feeling of detachment or what we already achieved from past few births/last birth, So we feel dettached towards ketu signification. Rahu is our desire what we desired and now we are here to fullfill that obsession whether we made it consciously or unconciouslly, But it all coming from Mind( Moon) and on other hand Saturn's role is to deliver results as per our karma.
Just a thought though.
So knowing what we are here to learn really helps attend that part of life with consciousness or atleast take serious responsibilities towards those parts of life. Those are my personal thoughts and whatever I perceived. If any learned members can verify those information/thoughts and guide further, I would be really grateful.
