"The concept of 'not begrudging one's life' appears in the 'Encouraging Devotion' (13th) chapter of the Lotus Sutra, when the bodhisattvas make a vow to selflessly spread the Mystic Law after the Buddha's passing (cf. LS13, 191). In 'The Selection of the Time,' the Daishonin elucidates the path of shared commitment of mentor and disciple, the path of refuting the erroneous and revealing the true, the path of attaining enlightenment in this lifetime--at the heart of which lies the path of 'not begrudging one's life.' If we give our all unstintingly to our Buddhist practice, proof of victory will be forthcoming--this is the unshakable conviction with which the Daishonin urges his disciples to 'try practising' (WND-1, 583)."
