Sathabhishekam is a sacred ceremony performed when a person completes 80 years and steps into their 81st year. It is a grand celebration of longevity, wisdom, and blessings, marking an important milestone in life. Typically organized by the couple’s children, in-laws, younger siblings, or close relatives, this pooja is one of the most significant rituals in Hindu traditions, seeking divine grace for continued health, peace, and prosperity.
