कार्यभूतो यथाकाश एक एव न हि द्विधा ।हेतुभूतस्तथात्मायमेक एव विजानतः ॥ ६ ॥
In plain words
Space is only an effect, a thing produced — and even so it is one, never split in two. This Self is the cause, and it too is one, one alone: so it stands for anyone who really knows.
Close to the Sanskrit
Just as space, being an effect, is one alone and never twofold, so this Self, being the cause, is one alone — for one who knows.
