Answer

During Siddhitap Beyashna in Chaumasa, it is generally not advisable to use soya sauce.

Explanation

In Jain tapasya, especially during Chaumasa and stricter practices like Siddhitap, food is expected to be:

• Simple and sattvik
• Freshly prepared
• Free from questionable ingredients
• Not fermented or heavily processed
• In line with the rules given by your Guru Maharaj / Guru Ma

Soya sauce is usually fermented and commercially processed. It may also contain ingredients that are not suitable for Jain dietary discipline during tapasya.

Spiritual Understanding

The purpose of Siddhitap Beyashna is not only limited eating, but also control over taste, simplicity, purity, and discipline. Avoiding items like soya sauce supports the inner spirit of tapasya.

Takeaway

It is best to avoid soya sauce during Siddhitap Beyashna in Chaumasa. For final guidance, follow the specific niyam given by your Guru Maharaj / Guru Ma, because tapasya rules can vary by tradition and instruction.
