The Sanskrit term for Ascesis is ‘tapas’, which means both ‘to discipline’ and ‘to make glow’.   Ascesis is about discipline and glowing, achieving a higher state of experienced intensity.   This is effectively an eternal dimension of philosophy; philosophy’s history has produced no progress with respect to Ascesis.  On the contrary, this aspect has mostly been forgotten.  And philosophy’s failure here is something more profound than Heidegger’s account of the forgetting of the true nature of being, though the latter points in the right direction.  Heidegger’s Being is still a forgetting of Ascesis, given that it is clothed in the tragic pathos of finitude (which is still a forgetting of tapas).
