7.6.5

ततो यतेत कुशल: क्षेमाय भवमाश्रित: । शरीरं पौरुषं यावन्न विपद्येत पुष्कलम् ॥ ५ ॥

tato yateta kusalah ksemaya bhavam asritah sariram paurusam yavan na vipadyeta puskalam

bhavam asritah
who is in material existence
sariram

Therefore, while in material existence (bhavam asritah), a person fully competent to distinguish wrong from right must endeavor to achieve the highest goal of life as long as the body is stout and strong and is not embarrassed by dwindling.
