“Once you have entered the Stream, yon are irreversibly bound for Enlightenment, one could say; you have sufficient spiritual momentum to take you all the way. You may still have a long way to go, but you are now safe from any danger of losing what you have gained. It is therefore said of the Buddha’s ‘victory’, his attainment of Enlightenment, that it is irreversible. It cannot be undone. There is no outside power that can make a Buddha no longer a Buddha. This applies not only to the Buddha, but also to the Arhant, the Once-Returner, and the Stream Entrant – and of course the irreversible Bodhisattva. But until we have passed through that gate of irreversibility we are in a precarious position. This is why we need to make a constant effort in our spiritual life and also make sure that we are living and working in conditions that support our spiritual efforts. Until we have reached that point of no return, we need the most positive situation, the most helpful environment, we can possibly get.” BuddhismThe Path Of The BodhisattvaSpiritual Momentum Book:The Bodhisattva Ideal : Wisdom and Compassion in Buddhism Source: The Bodhisattva Ideal : Wisdom and Compassion in Buddhism
