Jain dharma mein jo vastu kisi ke hak ki ho aur use chori karke le li jaye, ise steya (चोरी) mana jata hai. Yeh paap hai aur ahimsa, satya, asteya, aparigraha ke viruddh hai.

Iska arth:

• dusre ke adhikar ki vastu lena,
• bina anumati kisi ki cheez rakh lena,
• ya chhal-kapat se uska nuksan karna.

Jain acharan mein astya ka palan bahut mahatvapurn hai. Isliye dusre ki sampatti, vastu, dhan, ya adhikar ka apaharan nahi karna chahiye. Sadhak ko hamesha satya aur ahimsa ke path par rehna chahiye.
