12 sathiya

In Jainism, the term "sathiya" refers to the Swastika symbol, which is considered very auspicious and holds deep spiritual significance. The "12 sathiya" refers to the twelve auspicious symbols (Dwadash Lakshan), but if you are specifically asking about the Swastika, here’s how it is explained in Jainism:

The Swastika (Sathiya) has four arms, each representing one of the four types of existence (gatis) a soul can be reborn into according to Jain cosmology:
1. Heavenly beings (Devas)
2. Human beings (Manushya)
3. Animal or plant beings (Tiryanch)
4. Hellish beings (Narak)

However, if you are referring to the "12 sathiya," you might be asking about the "Barah Bhavana" (12 Contemplations) or the "12 Vrat" (12 Vows) of a Jain layperson (Shravak). Please clarify your question if you are referring to any of these concepts.
