According to Osho, using rajas or tamas as the basis does not change the fruits—they arise as they must, often as suffering—but it changes you. The unaware identify with the pain and become miserable; the aware remain the witnessing presence, untouched. Whatever the guna, the liberating practice is the same: stand apart and watch—'I am the seer; pleasure and pain happen around me, not to me.'
Whether you're restless (rajas) or dull (tamas), results still happen, but if you simply watch and don’t call them ‘me,’ you won’t be dragged into suffering.
