A true sadhna begins with an objective to discipline mind through ascetic practices, as sadhak (practitioner) matures the clinging towards objective(s) of sadhna gradually loose their hold on sadhak. This is where sadhna becomes sahaj (UNSTRAINED,EASY) the burden of objective is lost and natrual flow of activity continues. Life continues but burden of objectives is lost forever. There will be ups and downs in life but since you are not burdened with objectives, you will be actor in the play and nothing more.
