To me, the first principle of life is meditation. Everything else comes second. And childhood is the best time.
As you grow older it means you are coming closer to death, and it becomes more and more difficult to go into meditation.
Meditation means going into your immortality, going into your eternity, going into your godliness. And the child is the most qualified person because he is still unburdened by knowledge, unburdened by religion, unburdened by education, unburdened by all kinds of rubbish. He is innocent.

What does Osho mean by meditation? He means becoming centered and obtaining the state of "no mind," that is, undoing the ego.
In A Course In Miracles, it is taught that "meditation" is a quieting of the mind but the quieting, in and of itself, does very little, without changing one's thought system from focusing on the world of the ego to the world of the Spirit which is the Oneness of God.
A Course In Miracles teaches that the method of changing one's thought system is to rise above resentment, judgment, grievance, blame, guilt, and fear. It is the ego which blocks our awareness of Love's presence which is our natural inheritance.
Osho says that "meditation" means going into your immortality, going into your eternity, going into your godliness. Osho says the child is the most qualified because the child hasn't been burdened by all the nonsense which we think is so important on the ego plane for a happy life.
In the Christian prayer, the "Our Father," it says, "And lead me not into temptation but deliver me from evil" it is referring to not taking the promises of the ego world seriously. In eschewing the temptations of the ego world we rest in the bliss of the Oneness of God.
Osho teaches that the first principle of life is to be brought to innocense again by "meditation," giving up our egoistic ways of resentment, judgement, desire, blame, playing the victim. We have the power to decide to reclaim our innocense by giving up the judgments of the world.
