The Timeless Moment by Warner Allen (also listed as H. Warner Allen) is a classic work of Christian mysticism and metaphysical reflection first published in 1946. 
In this deeply contemplative volume, Allen draws on his own mystical experience and philosophical insight to explore themes such as:
The nature of the “timeless moment” where the infinite meets the finite;
Union with God, the dissolution of ego‑bound self, and the inner journey of awareness.
How both the mystical tradition and metaphysical thought reveal the deeper reality beyond time and change. 
This edition is a valuable resource for seekers of mystical spirituality, students of Christian mysticism, and readers drawn to consciousness, transcendent experience, and the metaphysical dimension of faith.
