Krishna, asked Arjuna, the Sun God is far older than you are

How can I believe you instructed him in this wisdom?  4.4

 Arjuna, said Krishna, you and I have had many births

I can remember all but you cannot!  4.5

 I am uncreated and in imperishable form and the Lord of all that exists

Yet, I appear always in my energy form  4.6

 When and where righteousness declines and wrongness rises

I come down and manifest myself 4.7

 I appear again and again, age after age

To nurture the right and destroy the wrongdoer  4.8
