For a beginner in Digambar Jain tradition, these are good simple and foundational shastras to start with:

1. Tattvartha Sutra

- The most important Jain philosophical text. - Gives the basic structure of Jain Dharma: jiva, ajiva, punya, paap, asrava, samvara, nirjara, moksha. - Good for understanding core doctrine.

1. Ratnakarand Shravakachar by Acharya Samantabhadra

- Very useful for householders. - Explains right conduct, vows, and the daily Jain way of life in a practical manner.

1. Panchastikaya by Acharya Kundakunda

- A deep but important text about the five substances and the Jain view of reality. - Better after basic study of Tattvartha Sutra.

1. Samayasara by Acharya Kundakunda

- One of the most respected Digambar texts. - Explains the pure nature of the soul. - For a beginner, read it slowly with a सरल explanation or commentary.

1. Niyamasara by Acharya Kundakunda

- Teaches discipline, inner purity, and right conduct. - Helpful after basic philosophy is clear.

Best order for a beginner

• First: Tattvartha Sutra
• Second: Ratnakarand Shravakachar
• Third: Panchastikaya
• Then: Samayasara and Niyamasara

Simple advice

If you are starting fresh, do not begin with very deep texts first. Start with Tattvartha Sutra and Ratnakarand Shravakachar, because they give a strong base in Jain principles and conduct.
