Answer

To understand Jainism accurately in English, it is best to read a combination of:

• Introductory books
• Books on Jain philosophy
• Translations of important Jain texts
• Books on Jain ethics and practice

Here are some respected English books commonly used by students of Jain Dharma:

• “The Jaina Path of Purification” by Padmanabh S. Jaini
• “Jainism: An Introduction” by Jeffery D. Long
• “Jainism: The World of Conquerors” by Natubhai Shah
• “Outlines of Jainism” by J. L. Jaini
• “Jain Philosophy and Practice” by Acharya Mahapragya
• “That Which Is” by Nathmal Tatia — English translation of Tattvartha Sutra
• “Tattvartha Sutra” by Acharya Umaswati/Umasvami, with English translation and commentary
• “Purushartha Siddhyupaya” by Acharya Amritchandra, available in English translation
• “Samayasara” by Acharya Kundakunda, available in English translation

Explanation

If you are new to Jainism, a good reading order would be:

• Start with an introduction:
  Read Jainism: The World of Conquerors or Jainism: An Introduction to understand Jain history, Tirthankars, sects, ethics, rituals, and basic philosophy.
• Then study core philosophy:
  Read The Jaina Path of Purification. It is one of the most respected English works for understanding Jain doctrine clearly.
• Then approach scripture-based study:
  Read Tattvartha Sutra, especially through a reliable English translation such as That Which Is. This text is highly important because it systematically presents Jain philosophy.
• For deeper spiritual understanding:
  Study Samayasara and Purushartha Siddhyupaya, preferably with guidance, because these texts are philosophically deep.

Spiritual Understanding

In Jain Dharma, true understanding is not only intellectual. Study should lead to:

• Right faith — samyag darshan
• Right knowledge — samyag jnan
• Right conduct — samyag charitra

So while reading books is helpful, it is also important to reflect, practice ahimsa, reduce passions, and seek guidance from knowledgeable Jain teachers or monks/nuns when possible.

Takeaway

A good path would be:

Introductory book → The Jaina Path of Purification → Tattvartha Sutra → deeper texts like Samayasara.

This will give you a balanced and accurate foundation in Jain Dharma.
