Bhagavad Gita Chapter 11 Verse 32
भगवद् गीता अध्याय 11 श्लोक 32

श्री भगवानुवाच
कालोऽस्मि लोकक्षयकृत्प्रवृद्धो
लोकान्समाहर्तुमिह प्रवृत्तः।
ऋतेऽपि त्वां न भविष्यन्ति सर्वे
येऽवस्थिताः प्रत्यनीकेषु योधाः।।11.32।।



हिंदी अनुवाद - स्वामी तेजोमयानंद
।।11.32।। श्रीभगवान् ने कहा -- मैं लोकों का नाश करने वाला प्रवृद्ध काल हूँ। इस समय? मैं इन लोकों का संहार करने में प्रवृत्त हूँ। जो प्रतिपक्षियों की सेना में स्थित योद्धा हैं? वे सब तुम्हारे बिना भी नहीं रहेंगे।।


Kumara Vaishnava Sampradaya - Commentary
The word kala or time is derived from  kalayati  which  is  synonymous  with
ganayati which is to calculate or count. Lord Krishna declares  He  is  time
which controls the life span of all living entities and will determine  when
Duryodhana, Bhishma, Drona and other royal dignitaries along  with  all  the
warriors will expire. Lord Krishna presently exhibited the  terrible  aspect
of the visvarupa or divine universal form in order to show He  was  directly
pravritah engaged to complete the activity of their destruction. By  a  mere
miniscule fiat of His will, Lord Krishna can accomplish this action  without
the assistance of anything or anyone else  and  all  the  warriors  of  both
armies Kaurava and Pandava will soon  meet  with  their  destruction  except
Arjuna and his four brothers.
