The concept of understanding one’s life purpose is not mystical. It is humans that have made it so.
Living purposefully is as simple as when a fish swims in water and a bird soars up in the sky (with grace and colour). It is that simple. We find it hard to follow ours because we are under intense pressure to conform. To do something that is popular. Something that pays now and pays big.
Plants and animals don’t have that kind of pressure. They don’t have the misfortune that comes with independence of mind and the exercise of freewill. We should learn from them!
