Namaskaar Kumar ji,
The Graha ruling the Karana will be important to Judge the over riding Yoga for Fame, Power and position. See there may be many (more than one combinations in a chart promising a good yoga, the yoga in which the Karana lord is involved will be more predominant. Its effect will be long term.

The Sthira Karanas already fall in the Dosha criteria because they fall in the Tithis that are Flawed. The chandra is very close to Surya and suffers combustion like effects. Have you read or heard the story of Budha's birth?

Every Tithi is a creation because it measures the separation of the Mother and Father factor and has two Karanas. Sakthi separates or thinks it is seperate from Shiva and indentifies itself with some attributes, name, body etc. thereby becoming an Individual. This individualisation can take two forms. Either Shiva form (Karthikeya was born of Shiva sperm) or Sakthi form (Ganesha was born from Paaravati). Both the childrens are related to Prithvi. One being called Son of Prithvi and the other is the deity for Prithvi Tatwa in the Moolaadhaara.

Look at the image attached. It is an Icon of Lord Dakshinamoorti.
This is the form of Shiva as a Guru.
The two Luminaries (Prakaash Grahas) Surya and Chandra is adorning his crown.
Can we identify the Panchaangas in this Image?

Since today happens to be Mahaa Shivaraatri. It is the best day to write on this.
Each Tithi is 12 degrees span and this means the 12 Raashis.
The exact Raashi is found by the remainder.
Taking the Chart given as an example:
Longitude of Surya: 20degrees 38 minutes in makara i.e.290deg 38 min.
Longitude of Chandra: 359deg 05 min.

Subtracting Chandra from Surya we get: 68 deg 27 min
dividing it by 12 we get a quotient of 5 and a remainder of 8 degree and 27 minutes.
Which means it is the 9th Raashi - Dhanus.
This particular Raashi will give us the clue of the purpose of birth of this child. Every birth has a purpose behind it. This is the cause of Lord Shiva and Paarvati coming together.

There is a legend connected to this auspicious night. It was on this night that the Lord appeared as a Jyotirlinga. Thus the Raashi arrived at by the calculation given will be the Jyotirlinga (there are 12 Jyotirlingas) which lights up the purpose of the Natives life. Worshipping the Jyotirlinga will help the Native understand and align the purpose of her/his life.

The tvelve Raashis and its corresponding Jyotirlinga is given below:
Mesha: Raameshwar.
Vrishbha: Somanath.
Mithuna: Naageshwar.
Karka; Omkaareshwar.
Simha: Grushneshwar.
Kanyaa: Mallikaarjuna.
Tula: Mahaakaaleshwar.
Vrischika: Vaidyanaath.
Dhanu: Vishwanaath.
Makar: Bhimaashankar.
Kumbha: Kedaarnaath.
Meena: Tryambakeshwar.
