यदा भूतपृथग्भावमेकस्थमनुपश्यति ।तत एव च विस्तारं ब्रह्म संपद्यते तदा ॥
In plain words
When a person perceives the diverse existence of all beings as rooted in the One and spreading forth from that alone, he attains Brahman.
Close to the Sanskrit
When one perceives the separate state of beings as resting in the One, and from that alone the expansion, then he attains Brahman.
