Krishna is the real doer!

Verse 1.15.21 (Sirisha Mji):

* In this particular shloka, Arjuna is mentioning that: I have the very same Gāṇḍīva bow, the same arrows, the same chariot drawn by the same horses, and I use them as the same Arjuna to whom all the kings offered their due respects. But in the absence of Lord Kṛṣṇa, all of them, at a moment's notice, have become null and void.
* SP explains wonderfully that: one should not be puffed up by borrowed plumes. All energies and powers are derived from the supreme source, Lord Kṛṣṇa, and they act as long as He desires and cease to function as soon as He withdraws.
* Most of us don't realize this and think that we are the doer. But it is not at all so.
* BG 3.27 purport
* Material civilization without God, is like a child's play.
* As devotees too, we should be careful, cause in the mode of service we might be empowered in many ways. So we have to make sure that our false ego is not puffed up. We should be humble and know that it is all due to the mercy of Guru and Krishna.
* In the mood of tolerance, humility, we should always chant the Mahamantra.
* The empowerment is coming from Krishna.
* Another point is that we should not be envious of other people. We should appreciate their qualities as they are reflecting Krishna's mercy so well.
