Sāṅkhya of Creation and Annihilation
Sarga–Nirodha-viveka
यदुपादाय पूर्वस्तु भावो विकुरुतेऽपरम् । आदिरन्तो यदा यस्य तत् सत्यमभिधीयते ॥ १८ ॥
yad upādāya pūrvas tu bhāvo vikurute ’param ādir anto yadā yasya tat satyam abhidhīyate
Cuando algo toma una materia previa como causa y se transforma en otra cosa, y su origen y fin son esa misma base, a eso se le llama “real” (satya).
One may understand the purport of this verse through the simple analogy of a clay pot. A clay pot is formed from a lump of clay, which is itself prepared from the earth. In this case earth is the original ingredient forming the clay lump, and the clay lump is in a sense the original cause of the pot. When the pot is destroyed, it will again assume the designation clay and ultimately merge back into the earth, its original cause. In relation to the clay pot, clay is the beginning and final state; thus the pot is called real, for it possesses the essential characteristics of clay, which exists before and after the existence of the functioning instrument known as the pot. Similarly, earth exists before and after the clay, and thus clay may be considered real because it possesses the essential characteristics of earth, which exists before and after the existence of the clay. Similarly, earth and other elements are created from the mahat-tattva, which exists before and after the existence of the elements, which may be considered real because they possess the essential characteristics of the mahat-tattva. The mahat-tattva is ultimately the creation of the Supreme Personality of Godhead, the cause of all causes, who exists after all is annihilated. The Absolute Truth is the Supreme Lord Himself, who step by step gives meaning and character to all that exists.
This verse defines satya as that underlying basis from which transformations occur—what stands as the beginning and the end of changing states.
In the Uddhava-gītā teachings, Kṛṣṇa guides Uddhava in discernment (viveka), distinguishing changing forms from the underlying reality to strengthen detachment and devotion.
Recognize that moods, roles, and circumstances change; seek the steady foundation—spiritual identity and the Lord—so decisions aren’t driven by temporary transformations.
