This is one of the Sadhana Sampathi the Advata School of thought promotes. concentration of mind or balance of mind is said to be Samadhana. But, Samadhana is something more than concentration. It is not just focusing the attention on one thing but a dynamic process which include all activities. In Samadhana both our emotions and understanding are also involved and thus it results in bringing about greater joy & better understanding of the 'object' of our attention. The mind is quiet & at peace, yet fully awake & dynamic A person with this quality not only can understand what the teacher is talking about but also directly 'see' the thing. It indicates an integrated mind. Whether it is worldly activities or realization of the truth within we should have the ability to turn our entire attention wholeheartedly on one thing and keep at it till we understand & feel that thing properly. A person with Samadhana has this ability.
