Neech Bhang Raj Yoga generally indicates Greater Success after breaking the handcuffs of lowliness.
Irrespective of the positions of the other planets in the horoscope (this is the reason why only the concerned planets have been shown), This is a very strong Neech Bhang Raj Yoga in the horoscope as Venus is debilitated in the virgo zodiac and Mercury is in mool-trikona as well as exalted in the same house and is conjunct with Venus.
Although, the degree of the planets and combustion also play a major role.
Irrespective of the placements of other planets in this horoscope, a strong neech bhang raj yoga is being formed. Here we can see Venus is debilitated in the first house (virgo zodiac) and the owner of the first house (Mercury) is situated in the 10th house (in the Gemini zodiac)- in its own sign and in a kendra house from Lagna.
Here as well, the degree of planets and combustion matter.
Again, Irrespective of the placement of other planets in the horoscope, neech bhang raj yoga is formed here as Mercury the owner of the house of debilitation of Venus is situated in Kendra from the lagna.
Here, combustion of the planets and degree also matter.
