<1>Think about God, His universe, and His truths all the time, and love Him with all your might. Otherwise your attention will be diverted to the material world, mundane things, and you will fall into your lower nature (hell).
<2>So avoid anything that keeps your attention from Him. <3>Do good but do not be attached to the results of your actions and this external world. Then you might create a great treasure in heaven of the good deeds you have done. Your thoughts will then be there rather than on the material world, which results in attachments, attraction, desires, and greed (the four winds), and the end by-product is bondage and spiritual death, because "where your treasure is, there will your heart be also."
<4>The "eye" refers to the spiritual eye which was closed after the flood of Noah (for more detail, read The Base, The Essence, or The Holiest Book). If this eye becomes opened and you become completely concentrated and one-pointed on spiritual progress, then the door of knowledge (light) of the spiritual truth will be opened to you, and you will be filled with this light. <5>But if your concentration is directed to Maya, "thine eye be evil," then the door of truth will be closed to you, "thy whole body shall be full of darkness," you will be drowned in Maya and your lower nature, and that is where hell is, "how great is that darkness!"
<6>When the external world and its illusive promises become a person's master, then he has no choice but to hate the spiritual truth which discourages that attachment, or he will leave spirituality completely and go to Maya. <7>Also here the word "master" is used. Master means one who makes the person its slave. So only when the external world and attachment to it is so great that a person becomes its slave, is it bad. However, if it is used without attachment, we continue to progress toward higher consciousness in the middle of Maya, remembering the Lord, serving Him, seeing Him everywhere, and being His slave. <8>Only by being His slave can we avoid being the slave of Maya.
<9>So be content with what you have, and direct your energy toward doing His Will, "Your will be done on earth as it is in heaven." The only things you need are the minimum necessities, "give us our daily bread." The rest of life should be used for purification, "lead us not into temptation," by His Grace, "but deliver us from evil." <10>Then the Kingdom Of Heaven within and without will be established, the three Kingdoms Of Heaven will be His, and His "will be done on earth as it is in heaven."
<11>Also why worry? We are not our bodies. The body is meat (flesh) and it is just like a raiment (garment) that we leave behind after death. The only things that will be with us are our Souls and spirits. We have to be concerned for what is permanent, not what we have to leave behind. So we should progress to make our Souls become Pure Consciousness. The body should only be used for this end.
<12>If God will provide sustenance for the birds, which are much lower in the evolutionary Hierarchy, would not He provide it for the human who is much higher in His eyes?
<13>Be content with what God has provided and work on the beauty within to be(come) the beautiful being you were born to manifest (qualities of God). As lilies in the field are content with what has been given to them and they manifest their beauty in full, "That even Solomon in all his glory was not arrayed like one of these."
<14>If by surrendering and being content even lilies can receive such beauty, which have such a short life span and lower consciousness, then would not God manifest higher beauty, which is your Soul, through you? But to come to such a point of surrendering and being content in life needs much faith.
<15>One thing should be remembered -- that these things Esa was teaching to his disciples, or to those who give up everything to spread the word of God and His Messages (the Holy Men). These people should totally detach themselves from these things and be free to direct and concentrate completely on God's work.
<16>Let the worldly people be worried. For those who dedicate themselves to God, the minimum will be provided and such a people should be content, surrendered, and have faith that they will receive it, because "your heavenly Father knoweth that ye have need of all these things."
<17>Those who direct all their attention and concentration toward their spiritual progress and others' (first seek the Kingdom of God), "all these things shall be added unto" them. The worker is then worthy of his wage.
<18>So do not be worried about tomorrow. There will be enough problems each day that a Holy man would have to solve without having time for other things, "Sufficient unto the day is the evil thereof." Be here now.
