Due to power-failure signal, I had to stop abruptly. Hence here is an addendum:
When I did my marine engineering, one of my professors was a visionary. He instilled in me the above line of reasoning. He used to say that in his native tongue, the word for good conduct is sadachar which is a combination of two words (sada = always + char = performing something with 100% involvement). Such action is naturally good and effective and one who performs action in this manner is always happy, he is in kingdom of God—something that Jesus too implied.
He also said that the word for coconut is nariyal (from the root nar, man) which means both—man and coconut—have some things in common. Coconut has three eyes—two are useless and one real through which the sprouting happens. Similarly, man has two eyes which are in a sense useless as they are capable of seeing only the superficial, and has one inner eye of understanding that sees the eternal (essence) behind the ephemeral (details). One who sees himself as eternal spirit in material body, he will also see others as eternal spirits in material bodies—which would mean he would always see good in others and do good to others, and will never harm others and feel that no can harm him either. Also, coconut has a hard shell which symbolizes ego in man. When it receives a hard hit, the shell is broken—sweet water flows. So are with people—when they receive a hard hit, their ego is broken—after that sweet behaviour starts freely flowing. Thus egoless living means kingdom of God. This explains custom of breaking the coconut before house-warming ceremony which symbolizes the concept that “from now onward members of this family will live without ego bringing sweet behaviour.”
