In Jainism, the Ashtamangala are the eight auspicious symbols that hold spiritual and ritual significance. Traditionally, these symbols—such as the Swastika, Shrivatsa, Nandavarta, Vardhamanaka (pot), Bhadrasana (seat), Kalasha (pot), Minayugala (fish pair), and Darpana (mirror)—are prominently displayed during religious ceremonies, temple rituals, and auspicious occasions.

Placement of Ashtamangala:

• Ashtamangala are commonly used in the decoration of Jain temples, during rituals like Pratishtha (consecration of idols), weddings, and other religious functions.
• They can be drawn or displayed at the threshold of the house or near the entrance, especially during festivals or important ceremonies, as a sign of auspiciousness and to invoke blessings.
• It is considered appropriate to display them outside the house, particularly at the main entrance, to signify welcoming auspiciousness and positivity.
• However, care should be taken that the symbols are treated respectfully, not placed in areas where they can be soiled or disrespected (e.g., near footwear, garbage, or places where people may step on them).

In summary: Yes, according to Jain tradition, Ashtamangala can be kept or displayed outside the house, especially at the entrance, provided they are shown respect and are placed in a clean, prominent location.
