The Roman philosopher Seneca said:
"The willing, Destiny guides them; the unwilling, Destiny drags them".
It makes a lot more sense to embrace it!
What is Destiny? Let's dig into the concept of destiny. I'll give you real world examples.
There is not one of us but has his appointed position, and we are verily ranged in ranks [for service]. Islam. Qur'an 37.164-65
All appointments are from Heaven, even that of a janitor.
Judaism. Talmud, Baba Batra 91b
Shall I not drink the cup which the Father has given me?
Christianity. John 18.11
Mencius said, "Though nothing happens that is not due to destiny, one accepts willingly only what is one's proper destiny. That is why he who understands destiny does not stand under a wall on the verge of collapse. He who dies after having done his best in following the Way dies according to his proper destiny. It is never anyone's proper destiny to die in fetters."
Confucianism. Mencius VII.A.2
The order that God has arranged, mortal man cannot upset.
African Traditional Religions. Akan Proverb (Ghana)
The concept of destiny permeates just about every doctrine in the world. Destiny means the purpose you were born into the world to fulfill. It is the idea that there are predetermined events in your life that will be encountered despite your best efforts to avoid them. There has been a debate raging for centuries about two seemingly opposite concepts, that of destiny and that of free will.
I have reconciled the two in my own theory of existence. If we imagine a straight line, running from our birth, through our life to death, I would define that as destiny. If we imagine a sine wave running across that straight line, I'd define that as freewill. When we follow our destiny things always seem to go right, "synchronicities" occur and everyone thinks we live a charmed life. When we make choices that are out of alignment with our destiny, we have a break down, where things seem to conspire against us. Life seems hard and we say, "What's the use?" But there is a corrective action, when we stray we are guided, sometimes gently and sometimes severely back to our purpose. This isn't to be taken as a punishment, but rather a rebalancing.
