Ashtamangal (eight auspicious Jain symbols) are traditional symbols described in Jain scriptures and widely used in worship and ritual offerings. They are the same set recognized by both Śvetāmbara and Digambara traditions, though exact interpretations or emphasis can vary slightly by tradition.

The eight symbols and their basic meaning:

• Swastika (श्वस्तिका): symbol of the four destinies (human, divine, hell, and other beings) and overall prosperity and progress.
• Shrivatsa (श्रीवस्त्र/श्रिवत्सा): a mark on the chest of the Jina, signifying beauty and the auspicious heart-nature of the Tirthankar.
• Nandhyavarta (नन्द्यावर्त): a complex, large swastika with nine corners, representing various forms of wealth and sacred wealth in mythic lore.
• Vardhamanaka (वर्धमानक): a shallow dish or lamp-stand symbol, signifying increase of wealth, fame, and merit through the Lord’s grace.
• Bhadrāsana (भद्रासन) / Bhadrasana (Sinhasana): the throne; sanctified by the feet of the Jina, symbolizing auspicious rulership and stability.
• Kalasha (कलश): a holy pitcher, symbolizing auspiciousness, wisdom, and fullness.
• Minyugala (मिन्यूगला) / Minyugal: a pair of fish, symbolizing protection and the auspicious arrival of grace.
• Darpana (दर्पण): a mirror, symbolizing clarity and self-reflection.

Key practice:

• The symbols are traditionally drawn with pure unbroken rice grains before the image of the Tirthankar, as described in Kalpasutra; sometimes people simplify the practice to drawing a swastika with three rice heaps representing knowledge, vision, and conduct. ( jainknowledge.com)
