Jainism ke anusar, jivo ki sankhya (praniyon ke varg ya jatiyon ki sankhya) batane wale Jineshwar ko "Ativeer" kaha jata hai.

Ativeer ka arth hai—jo atyant veerta ke sath jivo ki vibhinnata, unke gun, aur unki sankhya ka varnan karte hain. Aise Jineshwar (Tirthankar) jinhe sabhi jivo ki paryapt jankari thi, ve Ativeer kehlate hain.

Yeh visheshan Tirthankaron ko diya jata hai, kyunki unhone samyak darshan, samyak gyan, aur samyak charitra prapt karke sabhi jivo ki sankhya aur unka gyan prapt kiya tha.
