Where should it fall?
आकृष्टिशक्ति · स्वभाव · निराधार
Every cosmology owes an answer to one child's question: what holds everything up? The Sanskrit texts answer it four times over, each answer better than the last. The purāṇas tie the sky to Dhruva with cords of wind and notice the question exactly. The siddhāntas set a globe in empty space and declare it self-supported. And in 1150 CE Bhāskara finishes the argument with two moves a modern reader will recognize: a natural power in the earth that DRAWS the heavy toward it — so that falling is appearance, attraction the fact — and a symmetry argument for why the earth itself, in uniform space, has nowhere to fall at all.
Every quote is a slice from Jñānakośa, the research database behind this atlas; each links to the e-text it was sliced from. Translations are literal renderings; dates are approximate spans of compilation.
Bound, and not falling
न पतन्ति · the question noticed
The purāṇic sky is a machine of wind-cords anchored to the pole star — and the Skanda-purāṇa states plainly what the cords are FOR:
The explanatory slot is open and named: something must keep the luminaries from falling. Cords answer it for the sky. The earth needs a different answer.

The globe that holds itself
खमध्यस्था · the self-supported globe
Āryabhaṭa moves the pivot from Dhruva to the planet itself — the earth as the threshing-post of its own turning, suspended at the centre of space:
And the Sūrya-siddhānta gives the doctrine its canonical verse: the globe of the earth stands in the void, bearing an utmost power of upholding — the very verse Bhāskara's commentators will cite by name:
The power that draws
आकृष्टिशक्ति · 1150 CE
Then Bhāskara's Golādhyāya closes the argument. First the metaphysics: powers inhere in things — heat in fire, cold in the moon, motion in wind — and stability is the earth's own nature. Then the physics: the earth possesses ākṛṣṭi-śakti, a power of ATTRACTION, by which the heavy is drawn toward her and only SEEMS to fall. And last the symmetry: in space uniform on every side, where should the earth herself fall?
This is not Newton — there is no mutuality, no measure, no claim that the same power moves the moon. But the slot that gravitation fills is here filled by a named natural power, argued from symmetry — five centuries before the Principia, in a working astronomy textbook.
The slot and its fillers
Cords of wind, a divine peg, a self-supporting globe, a power of attraction: four answers to one question, each keeping what its predecessor got right. The cords knew something must act; the pivot knew it need not be external; the siddhānta knew the earth stands in void; Bhāskara knew that falling is relative to a puller, and that symmetry silences the question of the earth's own fall. When gravitation finally arrived with quantity and universality, it did not so much displace these answers as pay off a question they had kept open — and kept precise — for two and a half millennia.
Each quote carries its full citation, edition, revision-pinned source link and confidence grading in Jñānakośa — batch gola-gravity-pass1 (which unmasked a title-homonym e-text and fetched Bhāskara's real Golādhyāya from its scans) with the standing cosmography passes. Drop something tonight and watch it: Bhāskara would say the earth just pulled it home — and would ask you, with a smile, where exactly YOU think the earth should fall.
