According to Osho, a yogic kriya can certainly help, and there’s no harm in learning it, but it isn’t necessary. He recommends prioritizing the simple experiment he gave—practice it steadily for one month and watch. Direct awareness and consistent application matter more than collecting techniques; methods are aids, not the essence.
Yes, a kriya can help, but you don’t need it—just do the simple practice Osho gave every day for a month and see what happens.
