Answer

We mainly read about Siddha Bhagwan’s guṇas in these Jain scriptures:

• Tattvārtha Sūtra — the most important scripture for the nature of moksha and the liberated soul.
• Samayasāra, Pravachanasāra, and Niyamasāra by Acharya Kundakunda — these explain the pure soul and the Siddha state in depth.
• Gommaṭasāra — especially the parts related to jīva and siddha.
• Devotional stotras and bhakti texts dedicated to Siddha Parmeshthi — these praise the divine qualities of Siddhas.

Explanation

If you want the philosophical description of Siddha Bhagwan’s qualities, Tattvārtha Sūtra is the main scripture. If you want a deeper spiritual explanation, Kundakunda’s works are very important.

Spiritual Understanding

Siddha Bhagwan is the soul in its completely pure, liberated form. These scriptures help us understand:

• what the soul becomes after complete liberation,
• what qualities are revealed when all karmas are destroyed,
• and why Siddha Parmeshthi is worshipped as the ideal of perfection.

Takeaway

For Siddha Bhagwan’s guṇas, start with Tattvārtha Sūtra, and then read Samayasāra, Pravachanasāra, and Niyamasāra for a deeper Jain understanding.
