The Saint-Scientist Vallalar has a precise answer for what you came here for, which is what is a light body spiritually. Below, you will find the three stages of physical transformation Vallalar documented in his writingsβa path from a mortal body to one made of indestructible light. You may have heard this term used in ways that feel vague or symbolic, and that is understandable. Much of the writing on this topic remains metaphorical. Vallalar insisted his experience was a literal science, a repeatable process with observable results. To understand his claim, we first need to look at the man himself.
The Life and Teachings of Vallalar
Ramalinga Swamigal, known as Vallalar, was a 19th-century Tamil mystic whose collected writings, the Thiru Arutpa, remain one of the most extraordinary spiritual records ever produced. His life was filled with remarkable featsβthough he dismissed anything supernatural, insisting that everything he did was a science. He taught a path of universal compassion and self-purification, open to people of any faith or background. On January 30, 1874, accounts from those present record that he locked himself in a room in Mettukuppam and was never seen againβhis body never found. This event is documented by government records and by British Collector John Henry Garstin.
Beyond Metaphor: The Light Body as a Physical Reality
When modern spiritual teachings discuss a βlight body,β they often refer to an energetic field, a chakra system, or a visualization tool like the Merkaba. In some traditions, such as the Tibetan concept of the rainbow body, it is an advanced state achieved at the moment of death.
Vallalarβs teaching is categorically different. For him, the light body, or Gnana Deham, is not a metaphor, an energy field, or a post-mortem event. It is the final stage of a literal, physical transformation of the living human body. He documented this process as a science of compassion, diet, and devotion to what he called Arut Perum JΕtiβthe Vast Grace-Light. The goal is not to escape the body but to perfect it, rendering it immortal and indestructible while still alive.
The Path to a Pure Body (Suddha Deham)
The transformation begins with the Suddha Deham, or the Pure Body. This first stage is a process of physical and ethical purification. Vallalar taught that none of the advanced techniques can take root without Jeeva Karunyamβactive compassion that prevents suffering in other living beings. This is not a passive feeling but a guiding principle for every action.
The primary practice of Jeeva Karunyam is a plant-based diet. Vallalar taught that eating meat creates suffering for animals and introduces the energies of fear and death into the body, making higher transformation impossible. His manual for daily life, the Nithya Karma Vidhi, details a diet centered on simple, sattvic foods like rice, lentils, and stem vegetables.
Alongside this compassionate living, the central spiritual practice is the recitation of the Mahamantra. This is the call that invites the Vast Grace-Light to begin its work of purification within the cells. The mantra is:
AruαΉ Perum JΕti β AruαΉ Perum JΕti β
TaαΉi Perum KaruαΉai β AruαΉ Perum JΕti
This translates to:
The Vast Grace-Light. The Vast Grace-Light.
The Incomparable Great Compassion. The Vast Grace-Light.
What is a Light Body Spiritually? The Primal and Wisdom Bodies
After a period of dedicated practice, the Suddha Deham gives way to the Pranava Deham, or the Primal Body. This is an intermediate stage where the physical form becomes increasingly subtle. Those who reach this state, according to Vallalarβs writings, find their need for food, water, and sleep diminish dramatically. The body becomes luminous, resilient to disease, and begins to lose its mortal density. It is returning to a primal, uncorrupted state.
The final destination is the Gnana Deham, the Wisdom Body. This is the true light body. Vallalar documented this as his own state, one in which the physical body is completely transmuted into pure, intelligent Grace-Light. It is no longer subject to decay, aging, injury, or death. In his words, this body is all-knowing and indestructible, capable of appearing and disappearing at will because it is no longer bound by the gross laws of matter. This is the state that historical witnesses observed in his final years, culminating in his physical disappearance.
A practitioner following this path might first notice not a flash of light, but a simple, growing physical lightness after weeks of compassionate living and mantra recitationβa sign, Vallalar taught, that the bodyβs dense, mortal nature is beginning to yield to something finer.
Start with One Compassionate Meal Today
This entire path begins not with an esoteric ritual but with a simple, grounded act of compassion. Vallalarβs teaching makes the highest spiritual attainment accessible through everyday choices. The first step is to reduce the suffering one causes in the world.
You can begin this today. Replace one animal-based meal with a plant-based option from Vallalarβs Nithya Karma Vidhi. Choose simple foods like rice, lentils, or stem vegetables such as brinjal (eggplant) or drumstick (Moringa). This single act aligns you with the foundational principle of Jeeva Karunyam, the bedrock upon which the entire transformation is built.
