Verse
भूमिरापोऽनलो वायुः खं मनो बुद्धिरेव च ।अहंकार इतीयं मे भिन्ना प्रकृतिरष्टधा ॥
The five elements (conditions of material being – the solid, liquid, fiery, gaseous and ethereal), mind (with its various senses and organs), reason, ego, this is my eightfold divided Nature. This the lower. But know my other Nature different from this, O mighty-armed, the supreme which becomes the Jiva and by which this world is upheld
