If anyone has any information about this period, please share here. It is a broad subject... Mostly I am interested in particular sages, interesting doctrine, not focussing on self or Brahman. But feel free to share any relevant information on the times.
Wikipedia:
The word nirvana (Pali: Nibbana) was first used in its technical sense in Buddhism, and cannot be found in any of the pre-Buddhist Upanishads (It can be found in Jain texts). The use of the term in the Bhagavad Gita may be a sign of the strong Buddhist influence upon Hindu thought.[45] Although the word nirvana is absent from the Upanishads, the word itself existed prior to the Buddha.[118] It must be kept in mind that nirvana is one of many terms for salvation that occur in the orthodox Buddhist scriptures. Other terms that appear are 'Vimokha', or 'Vimutti', implying 'salvation' and 'deliverance' respectively.[119] Some more words synonymously used for nirvana in Buddhist scriptures are 'mokkha/moksha', meaning 'liberation' and 'kevala/kaivalya', meaning 'wholeness'; these words were given a new Buddhist meaning.[120]
I am looking for book discussing this (vedic/Indian setting) from Bhikkhuni Sobhana's list (just purchased Buddhist and Vedic Studies: A Miscellany Wijesekera). Suggestions appreciated.
