1 Gita Sloka  Every Day - Chapter 13 - Kshetra Kshetrajna Yoga - Sloka 23

Ya evam vetti purusham prakritim cha gunaih saha I

Sarvatha vartamanah api na sah bhuyah abhijayate II sloka 23

य एवं वेत्ति पुरुषं प्रकृतिं च गुणैः सह् I 
सर्वथा वर्तमानः अपि न सः भूयः अभिजायते II श्लोक 23 

He who thus knows the Purusha and Prakriti together with the gunas, is never born again, in whatever way he may live.

He who 'understands' namely, knows truly with discrimination, the self to be thus, and also the Prakriti as having the said nature along with the gunas, is never born again in Prakriti in whatever form or body he may be in, whether devas or men etc. The meaning is that at the time when the body ceases to exist, the self  will attain the purified state characterised by boundless knowledge and devoid of any evil.
