In Jain tradition, the concept of "16 Udharak" (उद्धारक) is associated with King Bharat, the eldest son of the first Tirthankara, Lord Rishabhanatha (Adinath). The word "Udhaarak" refers to those souls who attained liberation (moksha) or were uplifted (uddhar) due to King Bharat’s influence, guidance, or association.

According to Jain texts (especially in the Digambara tradition), King Bharat had 16 close associates or relatives whose souls were liberated mainly because of his spiritual influence and virtuous conduct. These 16 Udharaks are often mentioned in Jain literature, including the "Bharat Katha" and "Trishashti Shalaka Purusha Charitra" by Acharya Hemachandra.

The 16 Udharaks related to King Bharat are generally listed as follows:

1. Bharat Chakravarti (himself)
2. Bharat’s mother (Yashasvati or Sumangala)
3. Bharat’s father (Rishabhanatha/Adinath)
4. Bharat’s wife (Subhadra)
5. Bharat’s son (Arkakirti)
6. Bharat’s brother (Bahubali)
7. Bharat’s sister (Brahmi)
8. Bharat’s daughter (Sunanda)
9. Bharat’s teacher (Vishnu)
10. Bharat’s minister (Vijaya)
11. Bharat’s charioteer (Chandrasena)
12. Bharat’s friend (Pratihara)
13. Bharat’s elephant trainer (Mahamatya)
14. Bharat’s general (Senapati)
15. Bharat’s bodyguard (Pratihari)
16. Bharat’s religious preceptor (Acharya Sudharma or Sudharma Swami)

Note: The names and relationships might vary slightly across different texts and traditions (Digambara and Shvetambara). The central idea is that these 16 souls achieved spiritual upliftment or moksha due to their association with King Bharat.

Significance in Jainism: This concept highlights the importance of spiritual association (satsang), right conduct (samyak charitra), and the influence of virtuous souls in aiding others on the path to liberation.
