The 4th house in a Kundali represents home, mother, emotional foundation, inner peace, education, and property. It is the most intimate space of life, where one feels safe, rooted, and internally settled. When Mercury is placed in the 4th house, it brings intellect, communication, and analytical thinking into the emotional core of a person’s life.
