YOGA, I think is hard to be attained by one of uncontrolled self; but the self-controlled, striving, can obtain it by (proper) means.

asaṃyatā = unbridled; ātmanā = by the mind; yogaḥ = self-realization; duṣprāpaḥ = difficult to obtain; iti = thus; me = My; matiḥ = opinion; vaśya = controlled; ātmanā = by the mind; tu = but; yatatā = while endeavoring; śakyaḥ = practical; avāptuṃ = to achieve; upāyataḥ = by appropriate means.;
