Here are the basic points to keep in mind for a Jain Gruh Jinalay:

1. Purity and sanctity

- The Jinalay should be kept very clean, शांत, and sacred. - It should be a place only for bhakti, darshan, stavan, and dhyan.

1. Direction and placement

- Traditionally, the main idol is placed facing east or north. - The place should be in a calm part of the house, away from disturbance.

1. Separate and respectful space

- Gruh Jinalay should ideally be in a separate, quiet, and undisturbed room or corner. - It should not be used for storage, casual sitting, or non-religious activities.

1. Height and seat of Bhagwan

- The idol should be placed on a clean, respectful pedestal or sinhasan. - It should not be kept directly on the floor.

1. Clean materials

- Use simple, pure, and clean materials like wood, marble, or stone as per tradition. - Avoid decorative or flashy items that reduce the sacredness.

1. Minimal and serene decoration

- Decoration should be simple, tasteful, and non-ostentatious. - The focus must remain on veneration, not display.

1. Lighting

- Keep soft, proper lighting so the idol and space remain serene and visible. - Avoid very harsh or distracting lights.

1. Ablution and worship space

- If you perform puja, keep a separate clean area for puja items. - Maintain proper arrangement for jal, pujan samagri, and clean cloths.

1. No improper use

- Do not keep food, valuables, or unnecessary household items in the Jinalay. - It should remain a dedicated spiritual space.

1. Respectful conduct

- Enter the Jinalay with calm mind, clean body, and respectful behavior. - Maintain silence or soft devotion inside.

1. Tradition-based differences

- Some details may vary slightly according to Digambar and Shwetambar traditions. - It is best to follow the guidance of your Guru, Acharya, or local tradition.

1. Small but sacred is enough

- A Gruh Jinalay does not need to be large or elaborate. - Even a small, well-maintained, pure space is highly meritorious.
