San Juan de la Cruz (John of the Cross)

San Juan de la Cruz, or John of the Cross, was a 16th-century Spanish mystic and poet known for his spiritual writings and deep exploration of the soul’s union with God. A friar of the Carmelite order, he emphasized contemplative prayer, inner purification, and trust in divine love. His poetry and writings, such as "Dark Night of the Soul," describe the soul’s journey through darkness and purification toward spiritual enlightenment and unity with the divine. His insights continue to influence Christian mysticism, emphasizing that profound spiritual transformation often involves facing inner trials and trusting in divine grace.
