In Jain tradition, the threshold of a new home should be kept clean, pure, and simple.

General Jain guidance

• Keep the entrance free from violence, clutter, and negativity.
• The threshold is a place of auspicious entry, so it is usually decorated with:

- Swastik - Lotus - Om / Jain symbol in some traditions - Mangal kalash or simple rangoli, if done in a non-violent way

• Avoid any practice that involves:

- animal sacrifice - blood offerings - fire rituals with harm - superstition that goes against Ahimsa

For a new home

Jains generally prefer:

• clean entrance
• right-facing or respectful placement of auspicious symbols
• peaceful, sattvic atmosphere
• bringing in the house with prayers, samayik, or recitation of stotras, depending on family tradition

Important Jain spirit

The threshold should remind us that the home is to be entered with:

• Ahimsa
• Satya
• Aparigraha
• purity of intention

If you mean the exact ritual placement of a particular item at the new home threshold, Jain practice can vary slightly between Digambar and Shwetambar traditions.
