Basis of Drishti

Lord Brahma taught Rashi Drishti in circle.
Here is how to see:
(1) Draw a circle.
(2) mark point 1 at 15 degree left to verticle diameter.
(3) mark point 2 at 15 degree right to verticle diameter.
(4) point 1 and 2 will be at the top of circle separated by 30 deg.
These are signs Ar and Ta. Similarly continue to mark all signs at 30deg.
(5) Now as per BPHS,1,2 are in East,3 in SE,4,5 in South,6 in SW,7,8 in West,9 in NW,10,11 in North,12 in NE. These are seen clearly in above construction.
(6) Join 3-9 diameter. Draw 2 parallel lines on both sides of it.So 2-10,1-11,4-8,5-7 are joined.
(7) Similarly repeat with 6-12 diameter to get 5-1,4-2,7-11,8-10.
(8) East can see west and North can see South.
So join them to get12-9,1-8,2-7,3-6 and 3-12,4-11,5-10,6-9.
Now your Rashi-Drishti-Chakr is ready. You can see that each sign isjoined with 3 signs on which it has Rashi-Drishti. Thus Rashi Drishti is due to placement of signs in the sky in specific position.
Example: Consider a person(planet) standing on ground he can see something.Now if he is standing on hill,he will see something else.The person is same but his view has changed due to placement. This is Rashi Drishti.

Now consider a kid and a person. a kid being small,can see only a few things but the person being taller can see more. This is why inferior planets(Sun,Moon,Mercury,Venus) have only 7th aspect while superior planets(Mars,Jupiter,Shani,Rahu,Ketu)have additional aspects. Depending on their duties, they are placed in suitable orbits/inclinations so that they can see houses of their interest. Mars is commander so he has to protect Land(4th)and fight wars(8th). Guru(minister) gives Advice(5th) and tells Dharm(9th).Shani being servent, he has to do work(10th) assigned by boss and communication(3rd). Thus you can see Grah Drishti.

Now a person may see different somethings at different times at same place.eg. Some members read mails of specific persons only even though all mails are there on list.Some members are interested only in reply to their mails. So this will depend on thinking of person. This is seen in NakshatrDrishti.

Benefic/Malefic aspect gives good/bad results.
Different planets have drishti on different Nakshatr.
15th is common.Sun-14,15 Moon-14,15 Mars-1,3,7,8,15 Mercury-1,15
Jupiter-10,15,19 Venus-1,15 Saturn-3,5,15,19
Nakshatr also aspect other nakshatr like Rashi. This is seen in Sarvatobhadr chakr.
I will explain a short method for this.
(1) Draw 9 vertical and 9 horizontal lines.
(2) Ignoring the 4 corners of square,write krittika in top left.
(3) Continue from krittika in clockwise direction and write names ofall Nakshatr including Abhijeet after Uttarashadha.
(4) Nakshatr connected by straight line aspect each other.
This is also called SAPT-SHALAKA-CHAKR. It is used in Muhurtas.
Malefics should not aspect important Nakshatras at the time of Muhurt.
Since all drishties are mutually independent and work togather,they can be considered in all cases. Since BPHS uses only Rashi and Bhav,Drishties based on Nakshatr are not used for interpretation in this book.
Food for thought: A kid can sit on shoulder of person and see morethings.
So when two or more planets are togather,will they aspect more?

Argala

ARGALA means bolt.
Argala means a chain used to tie an elephant.
What is the use of bolt and chain?
They are used to fix door/elephant in proper place.
Argala also does the same thing.It keeps the results fixed.
The house/planet on which Argala operates,has to give itsgood/bad results with certainty.
So what is SHUBH/PAP Argala?
Both have same use.Both fix the results.
Does elephant find any difference if chain is of gold or iron?
It still remains fixed as before.So is result of bhav/grah.
Even though the elephant is not affected,the owner definatelyfeels better with gold chain.
Owner in chart is native.When shubh-Argala is there, he feels happy.
See, Argala(chain) can keep even the strongest animal like elephantfixed.
Similarly Argala can fix the results of all planets even ifthey are in full strength.
You can not divert their results in any way.VIRODH ARGALA is reverse.
we have to do exactly reverse procedureto tie and remove the chain.
So exactly mirror image house causeVirodh Argala.
They unfix or free the results of house/planet sothat they can give any other results/divert the results to othermatters.So virodh Argala can change results from good/bad to bad/good.
As explained earlier,benefics or malefics do not make any differenceto results but the feelings of owner are changed.Now if there is good result of a house/planet and following cases
occure:
(1)it has Papargala: Good results will occure definately but withtroublesrelated to matters of house in which malefic planet causing papargalaisplaced.
(2)it has Shubhargala: Good results will occure definately withhappinessrelated to matters of house in which benefic planet causingshubhargala isplaced.
(3)it has Papa in 2 and 12: Good results will be obstructed withtroubles related to matters of 2nd and 12th house in which maleficplanets are placed.If 2 is stronger than 12 then inspite oftroubles,good resultswill occure. However,malefics in 2/12 cause pap-kartary-yog so it canchange earlier good results into bad ones if dashas/transits are bad.
(4)it has Shubha in 2 and 12: Good results will occure definatelywith happiness related to matters of 2nd and 12th house in whichbenefic planets are placed.If 12th is stronger,then inspite ofhappiness,good results maynot occure. However benefics in 2/12 will cause shubh-kartary-yog soitcan boost good results even if dashas/transits are bad.
(5)it has Shubhargala obstructed by Papargala:Stronger will prevail.Since originally results are good,it will dominate in case ofequality.
(6)it has Papargala obstructed by Shubhargala:Stronger will prevail.Since originally results are good,it will dominate in case ofequality.Argala obstruction will occure only if obstructing planets are in themirror image quarter of the house.
In other words,if argala causingplanet is in 1/2/3/4 quater of house then virodh argala planet must bein 4/3/2/1 quarter of house to obstruct the argala,else there is noobstruction.
More planets means stronger argala/obstruction.
Virodh argala means obstruction but VIPREET ARGALA means forcedsuccess.there should be atleast 2-3 malefics in 3rd house to cause vipreetArgala.
Now if you have understood the meaning of argala(fixing) read it again and you will find everything is very obvious.This is the beauty ofSanskrit.It explains everything just by name.
I would like to remind the story of crocodile(Makar) who captured the footof an elephant.The elephant tried his best along with all his supporters but failed.All his supporters went away helplessly.He finally prayed to GOD. HE came and releived him by killing the crocodile and took both withHIM.They became Jay and Vijay who are door-keepers of Vaikunth.An elephant or Gaj indicates Guru(eg. Gaj-Kesari-yog).Guru is debilited in Makar and no one can rescue him there.Now,consider Makar as argala on Guru.It has fixed results ofGuru.Nothing can free him.Inspite of huge support from all planets, it can not be rescued.What is the remedy?
