The meditation period should last at least thirty minutes in the morning and thirty minutes at night. The longer you sit, enjoying the state of meditative calm, the faster you will progress spiritually. Carry into your daily activities the calmness you feel in meditation; that calmness will help you to bring harmony and happiness into every department of your life.Through daily practice of the foregoing instructions, you can prepare yourself for the practice of the deeper techniques of concentration and meditation that are given in the SelfRealization Fellowship Lessons. These scientific techniques will enable you to dive ever more deeply in the great ocean of Gods presence. We all exist at this very moment in that ocean of Spirit; but only by steadfast, devoted, scientific meditation may we consciously perceive that we are individualized soul waves on the vast ocean of Gods bliss.
