Answer

No, it is generally not compulsory in Jainism to touch the feet of a muni. Showing respect is important, but the form of respect can be different—such as doing namaskār, bowing with folded hands, or greeting reverently.

Explanation

In Jain tradition, respect for sādhu and muni is very important because they follow a very high level of restraint and spiritual discipline. However:

• Touching feet is a cultural practice, not a strict compulsory rule for all situations.
• Many Jains show respect without physical touch, especially by:

- joining hands in namaskār - bowing slightly - speaking respectfully

• In some situations, physical touch may be avoided for reasons of:

- monastic discipline - cleanliness and non-attachment - tradition of the specific sangh or community

Spiritual Understanding

In Jain Dharma, the main भावना is vinay—humility and reverence. The outer gesture matters less than the inner feeling.

So if you cannot or do not touch feet, it does not mean disrespect, as long as your attitude is sincere and respectful.

Takeaway

Touching feet is not compulsory; respect is compulsory. In Jainism, sincere humility and reverence are more important than any single physical gesture.
