Mercury in12th house, read a post on mercury in the 12th wherein a rosy picture was painted and claimed that the elder sibling will help the native because it is 2nd from the 11th.
Now the question is how can mercury represent self or native?
Only when it is ascendant lord.
Has the neutrality of Mercury been considered?
Mercury is conditional benefic or malefic as it gives results of its association.
Question three by being in 2nd from 11th house, How the elder sibling will help?
Here only the bhava are being considered to evaluate the result which seems too far-fetched.
Astrology of this kind is misleading and negates all fundamentals and principles of astrology.
Mercury signifies intellect, speech, trade, commerce, communications, neurons, and maternal uncle.
Rule-When a planet is placed in 6th,8th, or 12th its significations suffer so the houses Mercury represents, the significations it represents will all suffer.
Suppose the 12th lord is Mars and it is also the lord of 5th.
Let us say that this Mars is in Leo and it aspects Mercury, now this means Mercury is related to the 5th and 12th lord Mars since the ascendant is Sagitarrius mercury represents the 7th and 10th houses, in Such a condition the house significations of the 7th and 10th will suffer but the Mercury being associated with a functionally benefic Mars will give mixed results good in phases and bad at times.
