Osho said this quote
“ Meditation is simply awareness without any effort, an effortless alertness; it does not need any technique. But your mind is so full of thoughts, so full of dreams, so much of the past, so much of the future—it is not here and now, and awareness has to be here and now. The techniques are needed to help you to cut your roots from the past, to cut your dreams from the future, and to keep you in this moment as if only this moment exists. Then there is no need of any technique. After Shiva’s Vigyan Bhairava Tantra, in these five or ten thousand years, nobody has developed a single method. The cathartic methods are simply to throw all your impatience, your speediness, your hurry, your repressions. ”
