Answer

In Jain tradition, the ladies’ charavalo / charola is often made square mainly because of practicality, modesty, and ease of use.

It is not because the square shape itself has a special scriptural rule or mandatory spiritual meaning.

Explanation

A square charola is useful because:

• It covers the lap and body neatly while sitting.
• It stays stable and does not shift easily.
• It is easy to fold and carry.
• It helps maintain cleanliness and discipline during religious activity.

In many Jain communities, men’s and women’s religious cloth items developed slightly differently due to usage, seating style, and modesty customs.

Spiritual Understanding

The main Jain value behind using such cloth is maryada, vinay, and shuddhi — maintaining respect, discipline, and purity during worship, samayik, pratikraman, or other religious practices.

The shape is secondary; the inner feeling of reverence is more important.

Takeaway

Ladies’ charola is square mostly for practical and traditional reasons, not because Jain scriptures require that exact shape.
