Intrinsic, essential nature. That which is inherent, natural, unchangeable, not acquired by chance but already true at birth for every mortal, every thing even.
- svarupa
A brief analysis of the term: Sva means one's own, oneself. Rūpa means form, shape, nature, appearance. In the case of truth: Your only own (sva) form (rūpa) is actually sat cit ānanda, existence, consciousness, bliss—three words to express the one free truth.
In the teachings, a phenomenon also has a svarūpa. It is then said: The svarūpa of fire is heat and light. Fire cannot exist without these intrinsic properties.
As for the reality of both jīva (individual living being) and īśvara, and even of jagat, the world, indeed of all objects, appearances, phenomena, you name it, that is what is called the svarūpa. The true nature of these concepts is śuddha caitanyam, pure, unalloyed consciousness. That is always the svarūpa for everything and everyone, whether you know it or not.
Just like fire, the concepts and objects of reality can never be separated from their intrinsic nature, even though Vedānta initially does so (seer, seen, dṛg-dṛśya) to sharpen the intellect, develop viveka, discrimination, and thus later be able to understand what svarūpa is.
