Jai Sri Ganesha,
Man need to learn to discriminate between the two at its first which need fair conscious state with truth of conscience,
Man need to learn from the nature both ways, its positive truth and negative facet,
Bee and housefly are the party to nature with huge difference in between, Bee sit on the fresh flower that pure edibles but house fly, generate meaningful favorable extract with pulse of self but the house fly,
Collective spirit of bee is notable chapter and their spirit to safe guard the hive add to the truth of living but the hazard and afflicted truth of house fly-hit and run to spread nuisance value, and bee is considered auspicious on many chapter of life but the housefly,
May Lord bless all,
Thanks please
