Avos Perek 3

Akabyah ben Mahalalel said: mark well three things and you will not come into the power of sin: Know from where you come, and where you are going, and before whom you are destined to give an account and reckoning. From where do you come? From a spoiled drop. Where are you going? To a place of dust, of worm and of maggot. Before whom you are destined to give an account and reckoning? Before the King of the kings of kings, the Holy One, blessed be he.

When you think of from where you came, your spirit will be humbled and you will hate pride. And when you remember where you are going, you will scorn the world, recognize that its superfluous luxuries are nothing and only be involved with it for the service of the Creator, may He be blessed. And when you put into your heart in front of whom you will be giving a reckoning, fear of the Heavens will be upon you.

And now, my son, understand and observe that whoever feels that he is greater than others is rebelling against the Kingship of Heaven, because he is adorning himself with His garments

What cause does one have for pride? Perhaps his wealth? "The Lord impoverishes and enriches" (I Samuel 2:7). Perhaps his honor? It belongs to God, as it is written (I Chronicles 29:12), "Wealth and honor come from You." So how could one adorn himself with G-d's honor? And one who prides himself in his wisdom surely knows that God "takes away the speech of assured men and reasoning from the sages" (Job 12:20). Thus, all are equal before God, since with His anger He lowers the proud and when He wishes He raises the low. So humble yourself and G-d will raise you up!

In all your actions, words and thoughts, always regard yourself as standing before God, with His Divine Presence above you, for His glory fills the whole world. Speak with fear and awe, as a servant in the presence of his master.
