The Saint-Scientist Vallalar has a precise answer for what you came here for, which is how to achieve immortality.
If you are asking this question, it is not an intellectual game. It comes from a deep and often painful place — the raw protest of the soul against the finality of loss, against the idea that everything we are and everyone we love will simply end. This is a search born from suffering, not curiosity. Vallalar understood this state completely.
While many traditions treat physical immortality as a metaphor, Vallalar presented it as a documented, achievable science. To understand how, we need to look at the man who claimed to have demonstrated it.
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 feats — though he dismissed anything supernatural, insisting that everything he did was a science. He taught that the divine was not a distant being but an accessible reality called Arut Perum Jyothi, the Vast Grace-Light.
On January 30, 1874, accounts from those present record that he locked himself in a room in Mettukuppam and was never seen again — his body never found. This event is documented by government records and by British Collector John Henry Garstin.
Immortality Is a Physical Process, Not a Metaphor
In most spiritual teachings, the body is seen as a temporary vessel to be discarded at death so the soul can be free. Vallalar’s teaching is radically different. For him, the ultimate goal was not to escape the body but to transform it into an eternal, indestructible form made of pure light.
Physical immortality was not a symbol for the soul’s survival or a myth from a distant past. It was the explicit, documented destination of the path he laid out in his thousands of verses in the Thiru Arutpa. He presented this transformation as a methodical, replicable science, one that works on the very substance of the physical form, changing it from gross matter into a body of grace.
This process is not a sudden miracle but a gradual evolution through distinct, observable stages.
The Unbreakable Foundation: Jeeva Karunyam
Before any physical transformation can begin, Vallalar insisted on one absolute prerequisite: Jeeva Karunyam, or active compassion for all living beings. He taught that the body is a condensation of consciousness, and it cannot become subtle and light-filled while it is built upon the suffering and fear of other creatures.
This principle is not an abstract moral guideline. It is a direct, physical law. Vallalar taught that eating meat, which involves the terror and pain of an animal, introduces dense, death-oriented vibrations into the body. These vibrations make the cellular transformation impossible.
Therefore, the first step on this path is the complete cessation of harm. This includes adopting a purely plant-based diet, as detailed in his text Nithya Karma Vidhi, and actively working to alleviate the suffering of any being one encounters. Vallalar taught that none of the advanced techniques can take root without Jeeva Karunyam — active compassion that prevents suffering in other living beings.
The Three Stages of the Deathless Body
Vallalar documented a three-stage process for the body’s transmutation. Each stage marks a fundamental shift in the body’s composition and relationship with the physical world.
The Suddha Deham (Pure Body)
This is the first stage of purification. Through a consistent practice of compassion, a sattvic (pure plant-based) diet, and devotion, the physical body begins to change. The gross elements of flesh and blood are refined.
Vallalar taught that in this stage, the body becomes free from disease, the need for sleep, and the production of waste. It develops a natural luminosity and fragrance. It is perfected as a human instrument, becoming an ideal vessel for the divine Grace-Light to enter and begin the deeper work of transformation.
As the Grace-Light intensifies its work, the Suddha Deham evolves into the Pranava Deham, or Primal Body. The body becomes increasingly subtle, almost transparent. It is no longer composed of dense flesh but of a primal substance of light and sound.
At this stage, the body is not subject to the ordinary laws of physics. It cannot be harmed by fire, water, or weapons. It becomes extremely light and can appear and disappear at will. This stage has some similarities to accounts of the Tibetan rainbow body, but Vallalar’s description is unique in its scientific precision and its final destination.
The Gnana Deham (Wisdom Body)
The final stage, which historical accounts suggest Vallalar himself achieved, is the Gnana Deham, or Wisdom Body. In this ultimate transformation, the physical form, having become pure light in the Pranava Deham stage, merges completely with the universal Grace-Light, Arut Perum Jyothi.
The body becomes a formless, eternal existence of pure consciousness and light. It is no longer a separate entity but one with the divine, capable of acting anywhere in the cosmos. This is the culmination of the path: not the destruction of the body, but its eternalization as a vehicle of pure divine intelligence and compassion.
A Practical Guide on how to achieve immortality
Vallalar did not present this path as a theory but as a set of practices. The transformation is driven by the invocation of Arut Perum Jyothi, the Vast Grace-Light, which is the divine force that performs the work on the body.
The central practice for invoking this light is the recitation of the Mahamantra:
Aruṭ Perum Jōti — Aruṭ Perum Jōti — Taṇi Perum Karuṇai — Aruṭ Perum Jōti
This translates to:
The Vast Grace-Light. The Vast Grace-Light.
The Incomparable Great Compassion. The Vast Grace-Light.
Reciting this mantra, combined with the foundational practice of Jeeva Karunyam and a pure diet, is the engine of the transformation. It is not a mental affirmation but a direct call to the divine intelligence to descend and begin its alchemical work on the cells of the body. A practitioner might notice, after weeks of compassionate living and mantra recitation, a feeling of physical lightness and inner clarity, which Vallalar’s teaching identifies as the first sign of the body’s response to the Grace-Light.
One Concrete Action You Can Take Today
Begin with the foundation. Before your next meal, consciously offer food to another living being. It can be a handful of grain for a bird, a bowl of water for a stray animal, or a meal for a person in need. Perform this small, selfless act of compassion. Vallalar taught that this is the true beginning of all spiritual work, opening the door for grace to enter your life.
