Meditation is a deliberate attempt to pierce into the higher states of consciousness and finally go beyond it. The art of meditation is the art of shifting the focus of attention to even subtler levels, without losing one's grip on the levels left behind.
The final stage of meditation is reached when the sense of identity goes beyond the 'I-am-so-and-so', beyond 'so-I-am', beyond 'I-am-the-witness-only', beyond 'there-is', beyond all ideas into the impersonally personal pure being. But you must be energetic when you take to meditation. It is definitely not a part-time occupation.
Limit your interests and activities to what is needed for you and your dependents' barest needs. Save all your energies and time for breaking the wall your mind had built around you. Believe me, you will not regret.
