Monism in Ayyavazhi centers on the affirmation that all existence is grounded in a single, absolute reality, referred to as Ekam or Vaikundam, “the One.” This ultimate reality is one, indivisible, and without a second; it is not merely the highest among many, but the sole, all-encompassing ground of being. What appears as a diversity of beings, forces, and worlds is understood as expressions or emanations of this one reality rather than truly separate entities. The many are thus held to be rooted in, and non-separate from, the One.

Within this vision, Ayya Vaikundar is revered as the supreme manifestation of that single divine essence. Other deities and spiritual beings are regarded as partial expressions of the same underlying unity, not as independent powers standing apart from the ultimate. The apparent distinctions between God, soul, and world are therefore provisional, belonging to the realm of appearance rather than to the deepest level of truth. Monism here asserts that these are ultimately identical in essence, even though they may seem distinct at the phenomenal level.

This framework also treats the multiplicity of the world as maya-like, in the sense that it veils the undifferentiated oneness of the divine source. Creation, individual souls, matter, and all forms of divine manifestation are viewed as different modes in which the one reality is experienced and symbolized. Spiritual life, accordingly, is oriented toward seeing through these layers of apparent difference to recognize the unity that already underlies them. The dissolution of rigid ego-boundaries and separative consciousness becomes a way of aligning with the truth that all things arise from, abide in, and ultimately return to the same Ekam.
