Mercury is influenced by its company
Mercury is impressionable. That is its gift and its trouble.
In a janam kundli it takes colour from the sign it occupies and from whoever shares that sign. Beside the Sun it can be proud and visible in speech. Beside the Moon it can be moody and quick to feel. Beside Mars it debates. Beside Jupiter it teaches. Beside Saturn it becomes careful, sometimes too careful. A reading that treats Mercury as a single personality type has not read Jyotish. Budha is a messenger. The message depends on the company.
Study, trade, siblings, and the nervous mind
Study, writing, commerce, contracts, and nervous speed often run through Mercury. The third house and the sixth, speech and daily skill, often show its work.
Siblings, neighbours, short journeys, and the craft of explaining: those questions pull Budha forward. A tangled Mercury can mean a mind that will not rest, or speech that arrives before the thought is finished. A clear Mercury can mean a living made from words, numbers, or the linking of people who would not otherwise meet. The whole chart decides whether the mind is a gift or a knot.
Retrograde Mercury is not the internet joke
Retrograde Mercury is a condition that must be read with its sign, house, aspects, and dasha. In a natal chart it may show a reflective mind, repeated study, or a way of thinking that does not follow the first answer offered.
A retrograde transit is shorter and may bring review, revision, or delay in Mercury-related matters. It is not a curse and does not explain every communication problem.
Ask about the way you think
A reading uses Mercury for questions about study, contracts, commerce, siblings, writing, speech, and the way you process information.
It also checks the houses related to the question and the dasha now running. Bring your date, exact time, and place of birth so your sidereal Mercury can be calculated, then ask about the Mercury-related matter you want to understand.
