Answer

Generally, no. Gupt Navratri of the Ashadhi month is not a standard Jain observance in Jain tradition.

Explanation

• Gupt Navratri is mainly associated with Hindu/Tantric traditions.
• In Jain Dharma, it is not counted as a traditional Jain festival or official observance.
• Some Jains may personally choose to fast, do swadhyaya, pratikraman, or devotional practices during that time, but that is an individual spiritual choice, not a common Jain ritual.

Spiritual Understanding

Jain observances are centered on:

• Ahimsa
• Self-discipline
• Tapasya
• Swadhyaya
• Pratikraman
• Vrat and restraint

So, unless a practice is part of Jain tradition or aligns with Jain vows in a clear way, it is usually not treated as a Jain religious observance.

Takeaway

Ashadhi Gupt Navratri is not traditionally observed by Jains as a Jain festival, though some individuals may observe personal austerities during that period.
