In plain words
Nāma-rūpa—name and form—were unmanifest. As they unfolded from this very Ātman, they became the name and form called Ākāśa. This first Bhūta arose from Paramātman like foam from clear water. Foam is not water, yet it is never seen apart from water; and the clear water remains unlike the impure foam. In the same way, Paramātman remains pure and clear, distinct from foam-like Nāma-rūpa. Thus the unmanifest pair first appears as Ākāśa.
Close to the Sanskrit
The two, Nāma and Rūpa, while unmanifest and then being manifested, became the name and form called Ākāśa from this very Ātman. The Bhūta called Ākāśa arose from Paramātman in this way, like impure foam from clear water. Foam is neither water nor altogether different from water, for it is not seen apart from water. Yet water is clear and distinct from foam, whose form is impurity. So Paramātman is other than the foam-like Nāma-rūpa: it is pure, clear, and unlike them. The unmanifest Nāma-rūpa, as they were manifested in the place of foam, became the name and form called Ākāśa.
