How to attain concentration? There are no short cuts. Constant practice is needed. In the beginning, it is a great thing if by chance we get even one or two minutes of concentration in an hour. We should make continuous and sincere effort without stopping until we gain one pointed concentration.
The tree can't emerge until the outer shell of the seed breaks. Similarly, you cannot know the Truth without totally destroying the ego.
When we take each step forward with positive thoughts and a smile, all good qualities will come to us and fill our being. Then God cannot possibly stay away from us.
