Death: Loss of 21 grams or else?

Flight of soul is just a loss of 21 grams or else?We can disagree whether its realism or pessimism to talk about death on any given day let alone this humid weekend. But we cannot disagree that death is the only reality of life. Some would argue that life is so beautiful, so cherish it till death do us apart. But time stands like a monster which was born with a bang & will end with a bang; yet only a relative term. For as long as time existed & may exist, in relation with origin of life, the total existence of a septuagenarian homo sapien sounds ridiculous & pointless unless we are able to correctly identify purpose of our sojourn on earth. In this purview, death is bigger than life. Billions of years before & billions after our brief seventy years on earth, death rules. Death seems to have an upper hand over life ironically on the issue of longevity. In the analogy of life like a flowing river, if death is evaporation then reincarnation starts to make some sense but its farfetched, fictitious and felonious. However, river culminating at the ocean where droplets of melting glaciers, morning dew, springs & brooks, sweet wells & sour saline reservoirs; all return home. Ostensibly, death is divorce of soul from body, in real, homecoming. Divorce is niether desireable nor smooth but legal. So its not divorce rather homecoming which should come about as seamless fusion. And it doesn't end there. From here on, its perpetual life; an answer to unanswered human quest for eternal life via alchemy, holy grail etc

The only thing we could ask for is smooth transition from this to next world because transition is inevitable but the question remains would it be smooth? The answer depends totally on how we lived.
We have experienced life & we know death because its the distance between The Creator & the creation. He keeps creatures humble by guaranteeing them death. So we can say that we know death; its when life ceases. But we what we are not familiar with is the transitory phase from life to death. Transition is not the same for each individual, it cannot be the same. Humans die from the embryonic state to few minutes & hours after birth to as long as Centenarians & counting. The death exprience of each human being has to be different from another because in cosmic settings every human is a unique entity. His sense of self never grows old, only his body grows old. This sense of self is totally unique set of preprogrammed instructions, all written within the range of his freewill. What a master stroke !!!
It is only but logical that transitory phase of each individual will vary for its uniqueness. The better the quality of soul the smoother the transition from this to next world.
For as beautiful as life is, it deserves to be cherished but then it also deserves a smooth transition & a brilliant follow up till eternity. This sounds like a perfect plan not just physical loss of 21 grams. 
Only Allah knows the whole Truth.
