According to astrological beliefs, on August 28, the day of Raksha Bandhan, Mercury—the planet considered significant for relationships with sisters and paternal aunts—will be in a 'combust' (asta) state. Mercury is said to play an important role particularly in relationships with younger sisters, and it is also linked to relationships with paternal aunts. In this context, Mercury being in a combust state on Raksha Bandhan, the special festival celebrating the sibling bond, is being interpreted in astrology as a sign to exercise some caution.
