In Jainism, "Sathiyo ki Vidhi" refers to the code of conduct or the principles for friends or companions. It is about the right way to behave and support each other in the path of spiritual growth.

Though there isn't a specific scripture titled "Sathiyo ki Vidhi," Jain teachings emphasize qualities and duties of good companionship such as:

1. Speaking truthfully and kindly.
2. Encouraging each other in virtuous deeds.
3. Avoiding quarrels and disrespect.
4. Supporting each other in overcoming passions like anger, attachment, and pride.
5. Practicing forgiveness and patience together.

These principles help friends to uplift each other towards liberation (moksha) by living a life of right conduct (samyak charitra).

If you want, I can provide detailed Jain teachings on friendship and conduct from scriptures like the Tattvartha Sutra or the principles of Sadavrat. Let me know!
