According to Osho, you reconnect with your inner child by allowing a conscious ‘second childhood’ to blossom: drop accumulated knowledge and conditioning, move into innocence, and live as a dance of presence. Be close to nature, playfully attentive, wonderstruck, and intensely perceptive. Through meditation and surrender (to a living master or life itself), let obstacles dissolve and be reborn into clear, joyous seeing.
Relax the grown-up mind, play and notice things like a child, and let meditation wash away the blocks so your natural joy returns.
