Saying why you are here
Every Hindu rite, from a short household puja to a multi-day wedding, begins in the same way. The priest pours a little water into the hands of the person holding the ceremony, adds rice or a flower, and recites the Sankalp on their behalf. In it the person names themselves and their lineage, places themselves in time and space using the traditional cosmological description — the age, the year, the season, the month, the fortnight, the day, the place — and states plainly what they are about to do and why. The water is then released. The intention has been made.
The word sankalp means resolve or intention, and the rite is exactly that. Hindu tradition holds that an action offered with a clear intention is different in kind from the same action done absent-mindedly. The Sankalp is where the family, not the priest, takes ownership of what follows. It is why, in a well-led ceremony, the priest will make sure the family understands what they are resolving before the words are spoken.
For British Hindu families the Sankalp is also the moment where practical questions come up. Which names should be given? What is our gotra? What should we say the purpose is? None of these needs to be a source of worry, and all of them are settled in the conversation before the day.
