Every great tradition has discovered that the path inward is also the path toward what is most real — that the mind, quieted, becomes a mirror for what cannot be spoken. Buddhist vipassanā, Christian centering prayer, Hindu dhyana, Sufi muraqaba: all are disciplines of attention, training the practitioner to be present to what is always already present. The inner path does not require a religion, but it has been kept alive by them.
Rumi
