Energy Conservation (Satkaryavada) – The Real Never Ceases to Be

The Concept The First Law of Thermodynamics states that energy cannot be created or destroyed, only transformed. The central idea of Vedic physics, as articulated in the Bhagavad Gita and Sankhya philosophy, is that ‘the unreal has no existence; the real never ceases to be’ . This means that Prakriti, the universe’s fundamental substance, is eternal. It changes form, from energy to matter and back, yet the overall ‘quantum’ of existence remains constant.

The Story In the 1840s, Western science finally realized that energy cannot be created or destroyed, only transformed. But this “new” law was actually the bedrock of ancient Indian physics. The Bhagavad Gita and Sankhya philosophy boldly taught Satkaryavada—the principle that “the real never ceases to be”. They understood that the universe is a closed system of eternal energy (Prakriti) that simply shifts form, from solid to light and back again. To the Rishis, cremation wasn’t an end, but a final act of thermodynamics—returning the body’s energy to the cosmos.

The Original Text

Sanskrit Shloka: नासतो विद्यते भावो नाभावो विद्यते सतः । उभयोरपि दृष्टोऽन्तस्त्वनयोस्तत्त्वदर्शिभिः ॥ Transliteration: Nāsato vidyate bhāvo nābhāvo vidyate sataḥ | Ubhayorapi dṛṣṭo’ntastvanayostattvadarśibhiḥ || Bhagavad Gita (2.16) Meaning: “The unreal (Asat) has no being (cannot come into existence); the real (Sat) has no non-being (cannot be destroyed). The conclusion about both has been realized by the seers of truth.”

 

Related Innovations The Bhagavad Gita explained the concept of Avinashi, which states that energy cannot be destroyed; it simply changes form .

Fun Fact This is why Indian cremation is considered a return to the elements: the body’s energy is simply released back into the universe.

The Modern Legacy This law ensures that chemical equations are valid and power plants can calculate how much energy they generate.
