Rutham, Satyam ऋतम्, सत्यम्? It appears in Maha narayana upanishad. ऋतं सत्यं परं ब्रह्म पुरुषं कृष्णपिङ्गलम् । ऊर्ध्वरेतं विरूपाक्षं विश्वरूपाय वै नमो नमः
Satyam is Truth, the stable basis, the unchanging core of everything.
Ritam is the dynamic arrangement of this Truth in terms of Time, Space and Causality.
The first is the unchanging Truth, the second is the Truth as it expresses and manifests itself in and through change.
Affectionately,
Alok Da
