One should strive for what is meant by this word called FREEDOM. Make it your daily mantra. Make it your livelihood.
Strive for freedom from your own self, this self that is so full of anger, fear, hatred and pride, this ego-self that is making judgments on others as well as on yourself. Strive for freedom, but not the freedom with judgement connected to it.
There is such a freedom of being your own true Self, a Self that loves, and loves without 'a reason' to love. It is the highest form of all love. Be that one Self who does action without thinking about it, that one Self that has no words that can explain what that Self is, It just Is.
It is the Self without a second. This type of freedom does not come easy. You have to work for it. This is the freedom that all should work for. It should start when one knows that this freedom exists. Then, put some kind of effort towards it. By meditating, contemplating and living this freedom, your way to happiness is found.
