Mercury in Aries: the first house for Aries rising

Every Aries-rising chart has Aries on the 1st house, the house of self, body and vitality and both an angle and a trine, the most important house in the chart. Aries adds speed, courage and a need to act first. Sun signifies this house by nature, so its condition adds to the picture. Mercury also has directional strength (dig bala) in the 1st. Because Mars governs the 8th as well, the 1st and 8th are linked in this chart.

Mercury in the 1st gives a quick, youthful and articulate person, curious about everything and skilled at adapting. Its dignity here: in a neutral sign, ruled by Mars. Its sign is neutral ground. Mercury is never more than about 28° from the Sun, so the Sun sits in this house or a neighbouring one; when they share the sign, a Budha-Aditya combination forms and Mercury's closeness to the Sun (combustion) is worth checking.
