If attachment is the conditioning factor, then non-attachment will become the unconditioning factor. If expectation leads you in misery, then non-expectation will lead you into non-misery. If anger creates a hell within you, then compassion will create a heaven. So whatsoever the process of misery, the reverse will be the process of happiness. Unconditioning means you have to understand the whole knotted phenomenon of human consciousness as it is.
