What is "balarishta"

Balarishta in Hindu astrology is one of the three basic Arishtas that can cause early death. These Arishtas are indicated by certain specific planetary situations or combinations or associations present at the time of one’s birth or at the time of query or at a particular muhurta or happening as are revealed by the Natal Chart or the Query Chart or the Muhurta Chart. It is a Dosha.
