Yes, Jainism is a profound philosophical system with many core concepts beyond those you mentioned. Here are some additional important concepts in Jainism:

1. Tri-ratna (Three Jewels): You referenced it—Samyak Darshan (Right Faith), Samyak Jnana (Right Knowledge), Samyak Charitra (Right Conduct)—the path to liberation.

2. Karma: Jainism teaches that karma is a subtle material substance that attaches to the soul (jiva) due to passions (kashayas) and actions. Liberation involves stopping new karma (samvara) and shedding existing karma (nirjara).

3. Jiva and Ajiva: All existents are classified as Jiva (living beings, souls) and Ajiva (non-living substances). Ajiva is further divided into pudgala (matter), dharma (medium of motion), adharma (medium of rest), akasha (space), and kala (time).

4. Panchastikaya: The five types of substances (dravyas): Jiva, Pudgala, Dharma, Adharma, Akasha.

5. Navatattva (Nine Fundamentals): These are: Jiva (Soul), Ajiva (Non-soul), Asrava (Influx of karma), Bandha (Bondage), Samvara (Stoppage), Nirjara (Shedding), Punya (Merit), Paap (Sin), Moksha (Liberation).

6. Leshya: The coloring of the soul due to mental and emotional states; six types are described, ranging from the worst (krishna leshya) to the best (shukla leshya).

7. Gunasthana: Fourteen stages of spiritual development that a soul passes through on the way to liberation.

8. Samyak Darshan, Jnana, and Charitra: Emphasized as the three jewels, but also elaborated upon in terms of types and progression.

9. Sallekhana: The voluntary, gradual reduction of food and bodily activity leading to peaceful death, considered a spiritual practice for advanced ascetics.

10. Ahimsa (Non-violence): The supreme principle, along with Satya (truth), Asteya (non-stealing), Brahmacharya (celibacy), and Aparigraha (non-possession); these are the five great vows (Mahavratas for monks, Anuvratas for laypersons).

11. Siddha and Arihant: Arihants are souls who have conquered inner passions and attained omniscience but are still embodied. Siddhas are liberated souls, free from all karma.

12. Ratnatraya: The three jewels, as above.

13. Samvara and Nirjara: Samvara: Blocking the influx of karma; Nirjara: Shedding accumulated karma.

14. Panch Parameshti: The five supreme beings: Arihant, Siddha, Acharya, Upadhyaya, Sadhu.

15. Fourfold Sangha: Monks (sadhus), nuns (sadhvis), laymen (shrāvaks), laywomen (shrāvikās).

All these concepts collectively form the rich philosophical core of Jainism and guide its ethical, metaphysical, and spiritual teachings.
