1. Planetary Strength: The isht dev and main planet are often associated with planets that are strong and well-placed in an individual's birth chart. This can be determined by analyzing various factors such as planetary positions, aspects, conjunctions, and placements in different houses.
2. Nakshatra: The nakshatra or lunar mansion in which a planet is placed can also provide insights into its significance. Certain nakshatras are considered more auspicious and powerful, and planets placed in these nakshatras may have a stronger influence.
3. Divisional Charts: Divisional charts, such as the Navamsa or D-9 chart, can offer further clues about the isht dev and main planet. The strength and placement of planets in these divisional charts can provide additional information about their importance.
4. Dasha Systems: The timing and duration of planetary periods or dashas can also be considered. The dasha of a strong and benefic planet can indicate its significance as the isht dev or main planet.
5. Yogas and Combinations: The presence of specific yogas or combinations involving planets can also indicate the isht dev or main planet. For example, the presence of a benefic planet in the 9th house or the formation of a Rajyoga can point towards a strong and influential planet.
6. Personal Factors: Individual experiences, beliefs, and spiritual inclinations can also play a role in determining the isht dev or main planet. Some individuals may feel a stronger connection with certain deities or planets based on their personal experiences and spiritual insights.
It's important to note that the analysis of the isht dev and main planet is complex and involves various astrological considerations. Consulting with a qualified Vedic astrologer can provide a more accurate assessment based on an individual's unique birth chart and personal circumstances.
