Sāmāyika
Sāmāyika is the vow of periodic concentration observed by the Jains. It is one of the essential duties prescribed for both the Śrāvaka (householders) and ascetics. The preposition sam means one state of being. To become one is samaya. That, which has oneness as its object, is sāmāyikam. Sāmāyika is aimed at developing equanimity and to refrain from injury.
