Pada 4 concludes the Samanvaya Adhyaya by examining the remaining Upanishadic passages that may still seem doubtful in their reference. Its purpose is to firmly establish that even descriptions involving the vital force, light, space, gods, and meditative states ultimately culminate in Brahman. The sutras continue the method of harmonisation, proving that no genuine Upanishadic teaching falls outside the vision of the Supreme Reality.
A major concern here is distinguishing Brahman from entities that may appear supreme in specific scriptural contexts, such as prāṇa, jyoti, or certain deities. While these may be presented as exalted objects of meditation, the sutras show that their highest significance lies in their symbolic relation to Brahman. Whenever the text attributes universality, immortality, causality, or transcendence, the reference is taken to be the Supreme and not a limited principle.
The pada also treats meditations involving the liberated path, the ascent of the soul, and the subtle relation between the individual self and the cosmic order. These passages are interpreted so that the seeker understands Brahman as both the final object of knowledge and the ultimate destination of spiritual ascent. Thus symbolic cosmology and inner meditation are united in one Vedantic vision.
The concluding discussions reinforce the central achievement of the whole first chapter: every significant Upanishadic statement, whether direct, symbolic, cosmic, or psychological, consistently points to Brahman. No diversity of language or imagery can break this essential unity. The many voices of śruti are shown to speak a single truth.
Overall, Pada 4 serves as the final seal on the doctrine of Samanvaya. By resolving the last apparent ambiguities, it completes the demonstration that Brahman alone is the subject matter of the Upanishads, the source of the cosmos, the inner Self of all beings, and the highest truth toward which all scripture converges.
