@ltdaleadergt,
Destiny refers to a predetermined course of events. It may be conceived as a predetermined future, whether in general or of an individual. It is a concept based on the belief that there is a fixed natural order to the cosmos.
In my studies I have considered the idea of destiny many times. Life is like a game of chess? a big game of chess with infinite pieces and infinite choices. These choices will open new paths to you and close off others. For example when a computer plays a game of chess, every time you move it looks at ever outcome for every game and takes a path that it feels with lead to victory. We might not sit around calculating ever step we take but each step leads to a different path. These paths affect us as well as other in the universe. I could give millions of examples but I will shorten this to one or two.
Consider the following and when I say consider I mean don't just read what I said consider the further paths and steps that could have opened or closed for some many entities. Hopefully this will give you the answer you are looking for.
You are walking in a park enjoying the day. You see a rock on the ground and think to yourself? People rollerblade on this path all the time and someone will end up hitting this rock and falling. So you pick it up?
After picking up the rock you throw it to the side and continue down your path. About the same time the next day a person on rollerblades does not fall on the stone that you moved and continues down the path. The rock that you removed from the path landed on the only exit of an ant hill which you didn't notice not intend to happen. The ants were closed in the hill until they were able to dig out from a different area. The path chosen by the ant lead them to area safe from the rock that had closed of the first exit but also right along the path of a rolling ball that a child was chasing. The ball stopped just after rolling over the exit and the ants went into a defensive stance to protect the freshly made exit. As the child follows the path of the ball he/she stopped to pick up the ball without notice of his/her foot being in freshly made and now being defended exit to the ant hill. The ants go up the child's leg and start to bit him/her. The child cries and the parent comes running. Unknown to anyone till just then the child was allergic to ant bits and was rushed to the hospital to be treated.
Considering the fact that you saved someone from falling because of a rock you caused the child to be hospitalized. You being the doctor on duty that day at the hospital find that as you enter the door for your daily job the nurse runs to you in a panic because there is a child near death with an allergic reaction to the 20 or so bits he/she received from an ant hill.
I will leave that story open for you to consider the endings but give you a small look into the alt to your choice. This is the second of an infinite number of paths you could have taken with all different effects.
You see the rock as before but decide to leave it. You are too busy enjoying your day to consider the effects of the rock laying there on the ground. The next day at about the same time a person trips over the rock you didn't move and you see this. You run over to help them and find yourself introducing yourself to the one you are going to spend the rest of your life with. The ants continued building their hill and made new exits in different locations designed for better structural integrity vs the stress of saving the queen and their lives. The child takes the ball from on the ground and runs back to their parent with a smile of happiness.
This simple path could have changed some many more lives or paths that would have been unknown to you. Maybe the child would have survived and later found a way to stop the life threatening effects of the ant bits in other people. Something you carry on your person that can instantly stop what would normally cause you great pain, expense, and maybe even death. So many other paths could have been created by this one act of destiny.
The idea of destiny in my eyes I the fact that you control some aspects of your life but others are put in your path by the effects of others and you must ether take that path or figure a way around it if you didn't already choice that path. Just as the child could have gone around the ant or quickly picked the ball up and ran back causing no ants to attack him, just as you could have not noticed the rock all together, just as the person rollerblading could have taken a different path on the same walkway, just as the guy walking down the path could have done the same thing but didn't cause the rock to land on the ant hill would have changed the paths of so many.
You control many paths in your life and your paths are unlimited but the effect of those paths and the effects of other paths can change your life without you even knowing it. This is what I consider destiny. Not a controlled or written path by the gods but a chaos of ever-changing events that paths that make our lives the way they are.
