This contribution investigates some philosophical notions that Śāntānanda Sarasvatī, a contemporary proponent of the ancient Vedantic non-dualism (an advaitin) presents. Also, how this vision (darshan) may contribute to current Philosophical investigation as a ‘Way of Life’ in Pierre Hadot’s terms. Living with and from a view of some beyond, some other, ‘sub specie aeternitatis,’ as he so famously puts it. Mahārāja Śrī Śāntānanda Sarasvatī (1913–97) was Shankaracharya of the Jyotir Math monastery, an instituted proponent of Shankara’s Advaita Vedanta from 1953 to 1980. He was a direct disciple of Brahmananda Saraswati (1871–1953), also known as Guru Dev and succeeded him as Shankaracharya for modern times. The author proposes to investigate some Advaita, non-dual philosophical notions that arise from the practice and application of the causal (i.e., ‘spiritual’ in Hadot’s terms) advice culled from the Sanskrit Upanishadic texts in the light of the published conversations Śrī Śāntānanda Sarasvatī held as from 1965 to 1993 (Śāntānanda Sarasvatī, Mahārāja Śrī, Conversations with Mahārāja Śrī Śāntānanda Sarasvatī, The School of Economic Science, London, 2017–19).
