Wisdom means that it gives you detachment, detachment from all that is selfishness, self-centredness, self-obsession, ego - all connected with self.

The Spirit which is within you is a collective being and once you are awakened into the light of Spirit, you become a collective being. That means, on your finger tips you can feel the centers of others also as you can feel yourself. By knowing yourself you know the self knowledge, the inner self knowledge and by knowing others you are in collective consciousness.

Now when you meditate, try to meditate in a sustained way, first of all sustain it. Then you find that you are getting into the state of Samadhi, means at a state where you start feeling the joy and the bliss of God's blessings, and then you start saying "O God, what a blessing, what a blessing, and what a blessing". Once you have reached that state then you have to realize "Who am I". Who are you? What are you? You are the Spirit. After establishing your sustained attention on the Spirit you'll develop a state where you'll be in a complete state of witnessing with joy.

This all-pervading power is the power of divine love. It thinks. It organizes. It plans. It loves. It is the one which is the subtle of the ether, you can call it. It is the subtle of the matter. It is the subtle of your emotions. It is the subtle of your mental power. It is the subtle of your evolutionary power, but all integrated and coordinated in complete synchronization.

Only after Realization you are connected with reality.

This is also the age of science and technology in which human beings have progressed beyond the stage of blind faith.
