The Saint-Scientist Vallalar has a precise answer for what you came here for, which is how to achieve a light body.
If you are searching for this, you are likely feeling the weight of the physical form in a way that has become unbearable. This is not a casual inquiry. It comes from a deep exhaustion with the bodyβs limitationsβits heaviness, its susceptibility to sickness and decay, and the constant effort it requires. It is a search for true freedom. Vallalarβs entire life was dedicated to providing a direct, scientific path to that freedom.
Much of the writing on this topic remains in the realm of metaphor or distant spiritual goals. For Vallalar, the light body was not a symbol; it was a documented, observable, and achievable physical state. To understand how he made this claim, we need to look at the man himself and the evidence he left behind.
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 established a center for feeding the poor that still operates today, serving free meals to anyone who comes, regardless of background. His central message was that compassion was the only true prayer and the key to physical transformation.
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.
The Light Body Is Not a Metaphor
In Vallalarβs teaching, the concept of a βlight bodyβ is not a poetic idea or a state of consciousness experienced after death. It is a literal, physiological transformation of the human body into a form of pure, intelligent light. He called this final state the Gnana Deham, or Wisdom Body.
This idea of physical transfiguration has parallels in other traditions, such as the Tibetan Buddhist teaching of the Rainbow Body, where a masterβs physical body dissolves into light upon death. Vallalarβs work is distinct in that he documented the process as a science of immortality to be achieved while living, detailing the specific stages and practices required. He presented it as the natural, intended evolution of a human being who lives a life of supreme compassion and purity.
For Vallalar, the body was not an obstacle to be discarded but a vessel to be perfected until it became an indestructible instrument of divine grace.
The Three-Stage Path: How to Achieve a Light Body
Vallalar outlined a three-stage process of physical transformation in his writings, including the Thiru Arutpa. Each stage represents a profound shift in the bodyβs composition, moving from dense matter toward pure light. This is not an overnight process but a gradual refinement fueled by specific daily practices.
Stage One: The Suddha Deham (Pure Body)
The first stage is the purification of the physical body. The Suddha Deham is achieved when the body is cleansed of all impurities that cause disease, aging, and decay. The primary method for this purification is a compassionate, plant-based diet. Vallalar gave specific dietary guidelines in his work Nithya Karma Vidhi, emphasizing foods that are light, easily digested, and free from any association with suffering.
This stage is not just about what you eat, but about the quality of your entire life. It requires cultivating mental purity, gentle speech, and ethical conduct. As the body purifies, practitioners often report feeling physically lighter, more energetic, and experiencing greater mental clarity.
Once the body is purified, the transformation into the Pranava Deham can begin. This is the stage where the physical form becomes increasingly subtle and begins to radiate its own light. The flesh and bone, now refined, start to take on the qualities of divine sound and grace.
This body is described as being golden in hue and no longer subject to the harsh laws of the material world. It does not cast a shadow, is impervious to harm, and does not require conventional food for sustenance. The practices that lead to this stage involve deep meditation on the divine light and the constant recitation of the Mahamantra, which infuses the cells with grace.
Stage Three: The Gnana Deham (Wisdom Body)
The final stage, the Gnana Deham, or Wisdom Body, is the complete transformation of the physical form into a body of pure grace-light. This is the state Vallalar himself is said to have achieved, as documented by witnesses who observed his physical form becoming increasingly translucent toward the end of his life.
This body is described as all-knowing, indestructible, and capable of being anywhere at will. It is the ultimate expression of a life lived in total harmony with compassion and divine grace. Vallalarβs teachings present this not as a miracle for one person, but as the final destination of the path he laid out for all of humanity.
The Foundational Practices for Transformation
The journey through the three bodies is not powered by esoteric techniques alone. Vallalar was clear that one single principle makes the entire transformation possible: Jeeva Karunyam, or compassion for all living beings.
He taught that none of these techniques can take root without a heart that actively works to prevent and alleviate the suffering of others. The foundational practice is to see the hunger and pain of another being and to act to relieve it. This active compassion is what purifies the soul and, in turn, the body.
The central mantra he gave to focus the mind and invoke divine grace is the Mahamantra. Its recitation is not a mechanical exercise but an offering of the heart.

One Step Toward a Lighter Body Today
The path to the Suddha Deham begins with a single, conscious choice. You do not need to change everything at once. Today, simply replace one meal that contains animal products with a pure, plant-based option as described in Vallalarβs Nithya Karma Vidhi.
Choose simple foods like rice, lentils, or easily digestible vegetables like gourds or leafy greens. As you eat, hold the intention that this meal is not just for your nourishment, but a step toward a body free from the energies of suffering. This small act of compassion toward yourself and other beings is the first step on the path.
