The quiet sounds of prayer are hardly quiet. The light and reflection are special in the early mornings. Today I visited Pre Ko, a temple part of the Roluos Group, a collection of monuments representing the remains of Hariharalaya, the first major capital of the Angkorian-era Khmer Empire. Known as the ‘Roluos Group’ due to its proximity to the modern town of Roluos, the ancient capital was named for Hari-Hara, a synthesis of the Hindu gods Shiva and Vishnu.
