Summary: Mental processes are accelerated, good time for studying, teaching, and communication. Be mentally flexible, cautious of any difficult aspects.
This interpretation is for when Transiting Mercury is going through your natal third house.
During this transit, mental processes are accelerated and often coincide with important decisions and/or the formulation of plans for the future. This time is very good to study, give lectures, teach and any other types of communication, such as phone calls, writing or receiving letters.
It is a very fast period, and it will be difficult to keep to yourself and stay calm, so you should be attentive, mentally flexible and ready for any new experience that may arise. If Mercury makes difficult aspects, it can cause difficulties in any type of communication or transportation, nervousness, mental hesitation, misunderstandings, and you must be careful when making important decisions or signing contracts.
