A proper Upashray construction layout in Jain tradition should support sādhanā, serenity, cleanliness, and simplicity. The design should be peaceful and conducive to meditation, svādhyāya, pratikramaṇ, and the stay of sādhu-sādhvī or lay devotees during dharma activities.

Basic layout principles

1. Location

• Choose a quiet, clean, and non-noisy place.
• It should be away from kitchen smoke, heavy traffic, slaughter-related activity, and pollution.
• The surroundings should encourage ahimsa and mental calmness.

2. Orientation

• Many Jain traditions prefer the space to be aligned in a way that is clean, open, and light-filled.
• The exact direction may vary by local custom, but the main goal is peace and discipline, not decoration.

3. Main hall

• Keep a simple central hall for:

- meditation - svādhyāy - dharmic discourse - pratikramaṇ

• The hall should be spacious, uncluttered, and quiet.
• Avoid excessive furniture or luxury.

4. Seating arrangement

• Seating should be simple and low, suitable for sitting in dhyān or dharma study.
• Maintain proper space for:

- sādhu-sādhvī - devotees - scriptural reading

• The seating should support discipline and humility.

5. Sanctity and cleanliness

• The Upashray must be kept very clean.
• Use of the space should preserve:

- silence - purity - restraint - non-attachment

• Avoid items that create distraction or indulgence.

6. Basic rooms/spaces

A functional Upashray may include:

• Main prayer/svādhyāy hall
• Space for pratikramaṇ
• Simple storage for scriptures and dharmic items
• Separate clean wash area
• Minimal sleeping/rest area if needed for sādhu-sādhvī, according to local tradition and rules

7. Simplicity in design

• The architecture should be modest, not luxurious.
• Avoid:

- flashy interiors - entertainment-type design - heavy ornamentation

• The atmosphere should remind one of vairāgya and discipline.

8. Ventilation and light

• Ensure good natural light and fresh air.
• The space should feel open, healthy, and suitable for long sitting periods.

9. Separation of activities

• Keep the Upashray distinct from:

- kitchen - dining - storage of worldly goods

• This helps maintain śuddhi and sacredness.

10. Respect for tradition

• In Jain practice, the exact arrangement may differ between Digambar and Śvetāmbar customs and also by local community tradition.
• So the final layout should be done with guidance from experienced Jain elders, sādhu-sādhvī, or trusted dharmic builders.

Simple ideal principle

A good Upashray is one that is:

• clean
• quiet
• simple
• disciplined
• non-attached
• fit for dharma practice
