Dust Particles and Life
Life is like dust particles.
A stream of air keeps floating dust particles in the air. They move along the direction of air. Settle somewhere for a while, once the wind stops. Again, another stream of air takes them along. There is no connection between dust particles. Just by chance, they come in contact with each other and separate again.
Similarly, souls keep on floating as a cosmic dust in this universe, guided by their own deeds. There is no connection between souls. Just they settle in some life with some other souls.
Those who realize this, develop relationship with God, those who don't keep getting guided by materialistic forces of money, power, prestige, position, lust and so on. Sufferings and birth in lower species is the outcome. Only the moments passed in remembrance of God are passed in some constructive work. Rest has no value rather it has negative value! Negative because these moments take you away from God, which means you are going away from happiness, joy and advancing towards sorrow and grief.
Life is like bubbles. Bubbless live for seconds. So is lifespan. It is very short.
No one knows when bubble would burst. No one knows when life would end. Life cannot be guarenteed even for a graction of second. Death never comes with prior appointment. Hence we must make most of our life by choosing spiritual path to make permanent gain to get rid of death forever.
