Sahaj is just a slight, easy shift in the practice..Probably something you are already doing.....my introductory lecture was great for understanding the metaphysics of the practice.
IMO: SSRS realized that we humans tend to be neurotic, and bring our neurosis into spiritual practices, so he promotes an easier more practical attitude to discourage all the fretting we tend to do. He also discourages people from becoming so intense (and self-interested) about their practice that they skip doing very important things - like taking care of their children. In the final analysis though, due to the basic flaws that all humans have, spiritual movements are more alike than they are different and successful practitioners dive for the pearls and leave the rest....
