Here is a simple, authentic overview of Jain temple/home shrine layout, and how murtis (idols) are typically installed and venerated in Jain practice. I’ll keep to core Jain principles and note where Digambar and Shwetambar traditions differ.

1) Basic layout of a Jain temple or home shrine

• Mulnayak or main Tirthankar image: The central, most revered idol placed in the sanctum (garbhagriha). This is the focal point for worship and rituals.
• Surrounding idols: Additional Tirthankar idols or other venerable figures are arranged around the Mulnayak in a respectful, orderly way. They are often placed on altars or in alcoves.
• Pradakshina path: A small circumambulatory path or raised platform around the sanctum so devotees can walk clockwise around the Mulnayak during darshan and devotional rounds.
• Sabha/assembly space: A hall or verandah (mandir or chaitya) where people gather for group recitation, sermons, or community worship.
• Shanti or pradakshina area: A quiet zone in front of the sanctum for individual meditation, pranayama, or Samayik (seasonal, focused meditation) practices.
• Cleanliness and order: The whole space is kept clean, orderly, and free from disturbance; shoes are removed before entering; lighting (lamps or lamps like diya or candles) is used in many temples and home shrines.
• Orientation and environment: A calm, clean, non-distracting atmosphere is preferred. Some homes/temples choose a north-east (Ishan) orientation for prayer spaces, but the exact placement is less important than reverence, cleanliness, and proper darshan.

2) Daily worship and ritual flow (what devotees typically do)

• Darshan: Pausing to view and honor the Mulnayak and other Tirthankaras with attention and respect.
• Puja and offerings: Light, incense, flowers, and simple offerings (pushpa—flowers; phala—fruits; naivedya—limited food offerings) are offered with a mood of gratitude and non-attachment.
• Vandana (salutation): A brief bow or prostration before the idols, reciting or mentally repeating the names of the Tirthankaras.
• Prayers and mantras: Short prayers or verses praising the Tirthankaras; in many homes/temples, community recitations or bhajans are held.
• Aarti: A simple arati (lamp ritual) is performed in many places, accompanied by bells or musical praise, followed by quiet reflection.
• Pratikraman and Samayik: On specific days, devotees may perform reflective practices like Pratikraman (confession and repentance) or Samayik (a fixed period of meditation and equanimity).

3) How murtis are installed (Pratishtha) and consecrated Note: There are differences in wording and emphasis between Digambar and Shwetambar lineages, but the essence is reverence, purification, and energizing the image with proper rites.

• Pre-installation preparation: The space and idol are purified (cleansing, sanctifying with water and auspicious substances). The site is prepared with proper placement and alignment for the Mulnayak and companion idols.
• Ritual authorization: A learned priest or a capable Jain "guru" (acharya or upadhyay) performs the rites, often with the guidance of traditional texts. The rites emphasize non-violence, purity, and intention.
• Pratishtha rites (high-level idea): The idol is ritually consecrated (energized) through a sequence of offerings, mantras, and symbolic acts that invite the Tirthankar’s auspicious presence into the image. This often includes:

- Bathing the idol with water or sacred liquids - Offering clothes, jewels, and other adornments appropriate to the tradition - Recitation of specific mantras and verses honoring the Tirthankar - Anointing with spirituous or fragrant substances in some contexts (where allowed) - Final declaration that the Mulnayak is now present to be darshaned and worshipped

• Differing emphases by tradition:

- Shwetambar: Images are typically clothed (vastravarna) and are treated as living representations of the Tirthankar. The ritual often emphasizes visual and devotional reverence, along with prayers and offerings. The presence of the image is considered central to worship in daily and ceremonial life. - Digambar: Statues are often depicted nude (digambar) as a sign of renunciation. The pratishtha emphasizes detachment and the formless spiritual qualities of the Tirthankar, with devotion focused on the liberated state shown by the idol. The energy is directed toward inner discipline as well as exterior worship.

• After-pratishtha practice: The idol is kept in a prominent, clean place, and regular daily worship begins or continues. The temple or home shrine becomes a place of darshan (seeing), dhyana (meditation), and devotion.

4) How murtis are venerated in daily practice

• Darshan: Devotees come to view the Mulnayak and other idols with calm, respectful attention.
• Pooja and offerings: Simple offerings (flowers, fruit, water) and light (lamp) are made with gratitude, not attachment.
• Reverent behavior: Speak softly, keep the space clean, and avoid disturbance of others’ worship.
• Prayers and recitation: Short mantras or prayers, sometimes sung as bhajans, are recited or heard.
• Prostrations and namaskars: Gentle bowing to the idols as an expression of humility.
• Pratikraman and self-discipline: On specific days, devotees may perform Pratikraman (confession and repentance) or reflect on non-violence, truth, and other Jain vows (mahavratas).

5) Home shrine guidelines (practical tips)

• Choose a clean, quiet corner and a small, dedicated altar or shelf to place the Mulnayak and other revered images.
• Keep the area neat and free from clutter; avoid placing statues in places associated with negativity or disturbance.
• Ensure proper cleanliness: wash the altar periodically, and use clean cloths and respectful coverings for the idols.
• Respect dress and portrayal: if your tradition uses clothed murtis (typical for Shwetambar), keep images modestly dressed; if you follow Digambar practice, respect the nude depictions and their symbolism.
• Daily practice: even a short, regular routine—darshan, a brief prayer, and a small offering—helps maintain focus on non-violence and spiritual discipline.

If you’d like, I can tailor these guidelines to a specific tradition (Shwetambar or Digambar) or provide a concise, step-by-step pratishtha outline for a particular temple or home shrine.
