Bambù

Sitting, doing nothing, with the mouth that speaks no word, inactive, with the tongue touching the palate, firm, without the vibration of thoughts with the mind that observes passively, without expecting anything in particular, felt a hollow bamboo. Suddenly, infinite energy will flow into you and you will be full of the unknown, the mysterious, divine. The hollow bamboo becomes a flute and the divine begins to play. When you’re empty there are no barriers that prevent the divine inside you.
(Osho)
