According to Osho, yoga techniques are provisional toys given because we insist on doing; they don't deliver the ultimate but tire out the doer and reveal the futility of effort. Used like a second thorn, they help remove the first—restless mind—then must be dropped. At that point, genuine meditation is simple watchfulness and patient waiting in silence, where what always is becomes apparent.
Techniques are training wheels to calm your busy mind; once you can quietly watch and wait, take them off.
