What should we do if we are not to accumulate knowledge or engage in practices like devotion and chanting?

According to Osho, drop all accumulations and let yourself become utterly empty; the first task is unlearning and cleansing the mind of doctrines and habits, like uprooting weeds before planting. Pass through this inner 'demolition' without adopting new beliefs on anyone’s authority; let your own seeing confirm it. In the silence of emptiness, fresh seeds of authentic life can sprout and right action arises.
