आशा वाव स्मराद्भूयस्याशेद्धो वै स्मरो मन्त्रानधीते कर्माणि कुरुते पुत्रांश्च पशूंश्चेच्छत इमं च लोकममुं चेच्छत आशामुपास्स्वेति ॥ ७.१४.१ ॥
In plain words
"Hope is greater than memory. Kindled by hope, memory learns the sacred formulas, does the rites, wishes for sons and cattle, wishes for this world and that world. Worship hope."
The commentators
Chāndogyopaniṣadbhāṣyam· bhāṣya
मपर्यन्तं जगच्चक्रीभूतं प्रतिप्राणि । अतः आशायाः स्मरादपि भूयस्त्वमित्यत आशामुपास्वेति ॥
In plain words
The universe, revolving around memory, operates within every living being. Therefore, hope is even greater than memory. Meditate upon hope.
Close to the Sanskrit
The world ending with memory is revolving in every living creature. Therefore, the greaterness of hope even beyond memory exists; hence meditate upon hope.
