Fear comes when our relationship to something is in danger
Let's look at some examples.
For the need to feel bad about anything is a response of judgement of others or your own judgements of yourself which come from the seeds of doubt that are planted in us by our "friends". And sure enough we become attached to the ideas of what our lovers and our friends say we should and should be doing. We no longer live for ourselves we live by the ideals and passions of others and then begin to fear criticism from them because we are attached to the idea of having superficial acceptance. But this kind of acceptance is not real because your pears are accepting you for living by their ways. While if you lived by what you felt was right you would not receive love from your friends or lover. What kind of friendship or love is that?
Let's look at some more.
So now that we have these attachments we must further our attachment to them to gain our security, so we Desire things to broaden our attachment to them. And these broadened desires bring about greater fears as we have worked hard to build our jobs our loves our bodies now we are even more afraid to lose them. Because we desire so much for them even though ultimately none of it is truly ours. Our attachments to these things we fear losing take away our attention from the only thing we really have and that is our selves. Our own inner self knowledge. And instead of focusing on our self knowledge we look at what we desire to bring about an even greater attachment to the things we are so afraid to lose.
What if you werent attached to your job, your spouse/significant other, your physical body. What would you be left with? Would you still fear these things? And if we arent focusing on these seemingly essential life principles what are we supposed to be focusing on? For without those what are left? What's left is YOU.
With self knowledge you have true security, your happiness your understanding and security are your own as they depend on nothing but you. The world is within and you realize your godhood. All is tended to, with no fear of loss you no longer attract loss to you (Law of Attraction). You understand that your higher self has everything you need. You go to god for what you want you dont have to ask for more hours, You dont have to go on heart breaking dates week to week. You can free yourself from burdening pains in your future by realizing just how good your condition is in this now moment and all moments to come.
But first one must free themselves from their attachments, buddhism is a big fan of detachment. Quiet those thoughts of this world and these things. Cut your cords by saying to yourself "In this moment now i cut all emotional physical and mental cords to all things of a lower nature" and say to your self "In this moment now i want and expect to know who i really am and be fully conscious in this moment now." And meditate, visualize just you and not just your body but that higher part of you that has nothing to do with these physical earthly things. Your higher self. Sit with your higher self often you will see who you really are what you desire for your purpose, instead of what you desire for the security of your attachments.
I hope this helps some of you. Most of this was inspired by Krishnmurti, but the stuff towards the end is more Law of attraction, power of now stuff.
