The 16 Phases of the Moon (Shodasha Kalas) in Hindu Tradition: A Comprehensive Analysis

Introduction

In the vast cosmos of Hindu astronomical and spiritual knowledge, the Moon holds a position of paramount importance. While modern astronomy recognizes eight primary phases of the Moon, ancient Hindu texts describe a more nuanced system of sixteen phases, known as the Shodasha Kalas. This elaborate system not only demonstrates the sophisticated understanding of celestial mechanics in ancient India but also weaves together astronomy, spirituality, and daily life in a remarkable tapestry of knowledge.
