How good are Rahu and Mercury in Scorpio in the 9th house?

9th house signifies father, gurus, teachers, long distance travelling, fortune, religious Ness, spirituality, trinal house

Scorpio sign signifies mysticism, occult knowledge, transformation, insecurities, fears, spirituality, in laws, hidden, private parts, sexual urges, etc

So when Rahu is with Mercury, Rahu will inflate the mercury and mercury will become more expanded with illusions, misconceptions, more selfish thoughts, and Rahu will also become Mars in Scorpio so it will give psuedo mysticism or occult knowledge. Rahu is in inimical sign so it will turn to have more malefic energy.

Mercury is in the Scorpio not comfortable and being soft planet, it will get detrimental effects when with Rahu in Scorpio sign in 9th house.

So native decision will be oriented with short cuts and misguided wrong decision related to higher knowledge and person may believe to have mysticism or religiousness but in reality it would be just an illusion or obsession. He want to project himself with occult or mystic knowledge which would not be there.

He may have troublesome equation with boss, teacher, gurus, and father.
