How do you know a person fully?
If I want to know one person fully.... Here is my friend here. So, just by looking at his form, I know something about him. His Rupa I know. Probably I also know his Nama. What about his guna and his Lila, his activities and his qualities ?

Because Krsna is known fully by Nama, Rupa, guna and Lila. So, nama and Rupa are easily available. But what about guna and Lila?

If we do not know guna and Lila of a person then that means we have incomplete knowledge about him.

So, when is a person's guna revealed?
If somebody is described as a kind person. Here is a kind person but you have never ever heard of any incident in which his kindness was displayed then you don't know his kindness. For you your understanding of kindness may be restricted by some incidents in your life.

If somebody is introduced as a humble person then what do you know about humility?
Our understanding of humility may be quite worldly. It might be Prakrta.

So what is humility?
It is understood only when we hear about exalted personalities who have displayed humility in all situations at all times.
