Answer

Yes — both are used in Jain Dharma.

The core philosophical classification is 7 tattvas:

1. Jiva
2. Ajiva
3. Asrava
4. Bandha
5. Samvara
6. Nirjara
7. Moksha

The 9 tattvas are:

1. Jiva
2. Ajiva
3. Punya
4. Papa
5. Asrava
6. Bandha
7. Samvara
8. Nirjara
9. Moksha

So the 9-tattva system is not a contradiction. It is an expanded classification where Punya and Papa are counted separately.

Explanation

In Jain teaching:

• 7 tattvas give the main philosophical structure.
• 9 tattvas are used in practical teaching to explain karma more clearly.

Why are Punya and Papa added?

• Because they are both important results of actions.
• They affect the soul’s journey.
• They help explain how bondage happens through good and bad karmic activity.

So:

• 7 tattvas = classical core list
• 9 tattvas = expanded practical list

Spiritual Understanding

In Jain Dharma, the purpose of studying tattvas is not only to count categories, but to understand:

• what binds the soul,
• what stops bondage,
• what removes karma,
• and what leads to liberation.

That is why different explanations exist. The essence remains the same:

• know the truth,
• avoid bondage,
• purify the soul,
• and move toward Moksha.

Takeaway

So yes, there is proper Jain basis for both.

If someone says 7 tattvas, they are correct. If someone says 9 tattvas, they are also correct, because they are using the expanded Nav Tattva classification.

If you want, I can also explain the difference between 7 tattvas and 9 tattvas one by one in very simple language.
