Do you remember when you were 5 years old and life was fun? Children are full of joy until someone or something stops it.
See, this is why you pose such questions....
If you were joyful you wouldn't be stopping what you were doing to ask what the point of life is, would you? Of course not.
The question I have for you is this: if your mind took instruction from you, would it be in a blissful state or joyless state?
What I am asking is, if you had a choice between being blissed out or depressed, which would you choose?
Obviously, you would choose to be blissed out, wouldn't you?
That means if you are not blissed out all the time, then your mind is not taking instructions from you. It is taking instruction from somewhere else.
I think you should take charge of your mind
