Sage Kambhoja or Kumbhoja (i.e. Kamboja)  finds reference in southern Indian recensions of Ramayana. He seems to have lived somewhere on the banks of river Godavari, in south-west India during Ramayana times. Ancient Sanskrit references indicate that ancient Kambojas were closely connected with Vasishthas . These ancient texts also reveal that the Kambojas and some other allied Iranian peoples|Iranian tribes from north-west came to the aid of Vasishtha clan at the time of crisis. It therefore, appears probable that Vasishthas may have acted as Purohits/religious teachers to the Kambojas and the latter may have regarded them as their spiritual guides or gurus . It also appears certain that the Vasishtha Brahmanas were chiefly responsible for the learning and scholarship found among the ancient Kambojas . Ramayana |Ramayanic sage Kumbhoja or Kambhoja appears to be a close friend of sage Agasti. Sage Agasti was brother of sage Vasishtha and was living as a hermit in Dakshinapatha. Rama Chandra (Shri Rama), Lakshmana (Shri Lakshmana) and Sita (Mata Sita) had paid visit to the hermitage of sage Kambhoja, from there they had proceeded to Panchavati during their Vanwasa period before Sita was abducted by Sri Lanka (Sri Lankan) king Ravana.
- In ancient history of India, a member of a tribe or its prince was also known after the name of his tribe (jana) or his country (janapada). In case of Kamboja tribe, Panini specifically states so in his Ashtadhyayi (Sutra IV.1.175). Thus from tribal name Kamboja came the personal name Kambhoja (Kumbhoja) which is the de-Iranianised version i.e southern Indian form of standard Kamboja.
