Krishna will test us everyday...

Verse 1.7.38-40: After Arjuna caught hold of Ashwattama, Krishna suggested Arjuna to kill him immediately, since he violated the code and conduct of the Battlefield. So Krishna incited Arjuna to kill Ashwattama.

In the sastras, he who attacks without notice or kills from behind or sets fire to another's house or kidnaps one's wife is condemned to death. Krishna therefore reminded Arjuna of these facts so that he might take notice of them and do the needful.

Lord Sri Krishna encouraged Arjuna outwardly just to test Arjuna's sense of duty. It is not that Arjuna was incomplete in the sense of his duty, nor was Lord Sri Krishna unaware of Arjuna's sense of duty. But Lord Sri Krishna put to test many of His pure devotees just to magnify the sense of duty.

Always everyday, we are facing tests from Krishna. And He wants us to pass every test, every day. When we pass, we make progress. But when we fail the test, we get a lower grade. At every test, Krishna and maya both are looking. How we perform determines our progress. That's why we should be very very humble. Then we will pass. That's why we should pray to Krishna always to give strength to pass the test.
