Apoornathvam-Desire

Apoornathvam means incomplete, which leads to desire in vedantic format. Why do we desire at all, we desire because we lack something, we lack, money, education, fame, power, wife, children, marriage of daughter, job for son, grand children etc. These are all finite things, so man being a finite entity collects finite materials such as above forgetting the fact,
Finite + finite = finite.
But he wants infinity (Poornathvam), which is the ultimate happiness.
We think that by getting all these we will be complete ie Poornathvam, which will give ultimate everlasting pleasure in life, which is the greatest fallacy man commits in the world. There is only one Poornathvam in the Cosmos ie GOD. If man realises GOD, he will have the everlasting bliss for rest of life, without any rebirth.
This is well explained in the Shanti Mantra of Isa Upanishad,
poorNamada: poorNamidam
poorNaat poorNamudacyate I
poorNasya poorNamaadaaya
poorNameva avaSishyate II

World&Vedanta!!

"World is neither a place of joy, nor a place of sorrow, it is only we who are responsible for our own joy & sorrow. Do not manipulate the external world of objects & human beings, adjust yourself to the surroundings, you will be ever happy" – Vedanta.

Human beings always got the tendency to blame world for all the miseries, forgetting the fact that what is misery for him is joy for someone & tend to get into quarrels by trying to change the world, ultimately ending in sorrow, spoiling One's day & mood.

Let us take an example; you are sitting in your living room engaged in some activity, one of the youngsters of the house starts blaring pop music which is annoying you, you request the youngster to stop his music, which he ignores, you start shouting at him, there starts a quarrel ultimately spoiling the mood of the house & everyone. If the youngster refuses to stop his music, best course is to leave the room to another place rather than picking up a quarrel.

Do not try to change / manipulate the external world & end in a misery.
