Samvara

Samvara ("saṃvara") is one of the "tattva" or the fundamental reality of the world as per the Jain philosophy. It means stoppage—the stoppage of the influx of the material karmas into the soul consciousness. The karmic process in Jainism is based on seven truths or fundamental principles ("tattva") of Jainism which explain the human predicament. Out of the seven, the four influxs ("āsrava"), bondage ("bandha"), stoppage ("saṃvara") and release ("nirjarā")—pertain to the karmic process.
Philosophical overview.
"Saṃvara" is the first step in the destruction of accumulated harmful karmas. The world or the "samsara" is often described as an ocean and the soul as a boat trying to cross it and reach the shores of liberation. The boat is leaking i.e. karmic particles are getting attached to the soul. Hence the first step is to stop the leak and prevent new water from entering the boat. This is "saṃvara". Jains assert that emancipation is not possible as long as the soul remains unreleased from the bondage of these karmas. Release is made possible by "saṃvara"; that is, the stopping of inflow of new karmas, and "nirjarā"; the shedding of existing harmful karma through conscious efforts.
