This is bizarre!  Using Sidereal changes everything -- planet signs, houses, angles, even my Sun sign.  How can someone born in mid-April suddenly be a Pisces Sun?  What is the criteria for choosing Sidereal vs. Tropical?

I'm pretty sure I'm doing this wrong, but just by going to astro.con & switching to sidereal (everything else at default), my Virgo stellium becomes a Leo stellium. I don't think that resonates with me...& I should know; my dad & brother are mega-Leos. I don't have shiny hair!

Check out your yogas in Vedic astrology. I have a ton. I’m sure everyone has a ton because there are hundreds…. My favorite yoga I have is called Raj yoga. I also have Sasa yoga, Neecha Bhang Raj yoga, Amla Yoga, Vimala Yoga, Maha Laxmi Yoga, Chandra-Mangala Yoga. The Neecha one is nice because it cancels out the bad affect of my debilitated Venus in the 10th in Vedic. When a planet in a debilitated planets rulership aspects that planet the bad affects get cancelled. I gave up on ever fully understanding Vedic cause it’s too complicated for me, but I still like to look into it sometimes. 

I pulled this from some website: but this is what Raj Yoga is:

Raj Yoga is an extraordinary power that is created because the lord of a ‘Kendra’ (one of the four houses in your horoscope – 1st, 4th, 7th & 10th) and the lord of a ‘Kona’ (one of the three houses in your horoscope – 1st, 5th & 9th) come together through a conjunction or exchange of houses or because they aspect each other.

A Raj Yoga bestows you with power and position when it combines hard work and action with one of the factors mentioned below (which is a source of the yoga):

• Wealth: The ability to use money and affluence as a tool to build up power and position.
• Real Estate: The ability to use land and real estate to control the destiny of others.
• Intelligence & Knowledge: The ability to use unique skills and intelligence that create intellectual property, which makes people seek out a leader.
• Partnerships: The ability to use the power of partnerships, cartels and marriages – that bring collective power.
• Pure Luck & Divine Blessings: The ability to use your talent, good nature, hard work, and endearing traits to put you at the top and head of things.
• Resources from foreign sources: The ability to use this for power and position.
• Religion: The ability to use religion as a tool for power.

What impact does Raj Yoga have on you?

• With Raj Yoga in your horoscope, you are born to rule – it makes you are a born leader.
• It gives you a destiny similar to the unique category of people who were Kings in ancient times and leaders of countries in today’s times.
• Raj Yoga is present in the horoscopes of rulers, leaders, businesspersons, influencers, financial leaders, bureaucrats, senators & legislators, heads of institutions, and diplomats. It affects many areas of life that bring success and prosperity.

Some famous personalities with Raj Yoga in their horoscope

• Narendra Modi (Prime Minister of India)
• Mahatma Gandhi (Father of the Nation, India)
• Barack Obama (Former US President)
• Sardar Patel (Indian Political Leader)

What should you do if blessed with a Raj Yoga?

• Misconduct will dim the good effects of a Raj Yoga; hence, it is vital to act in a manner that does not make the power of this extraordinary yoga vanish.

My chart makes a lot of sense to me in the sidereal system.

hmm I go from Pluto Rising in Scorpio to Libra and I become an Aries with a massive stellium in Pisces, hmmm
