Meditation is a process of unbroken flow of thoughts about some object. In this process of thought, in which the distinction between the meditator and the objects is still there. The Sadhak (meditator) is able to feel the difference between himself and the object.
It is a state of mind in which all the sense organs and the mind are restrained and concentrated towards the object on which one is meditating.
If a person is able to achieve this level of concentration then any knowledge about the object on which he is meditating comes to him in an automatic way.
This is a very fine state of mind and once he reaches it he is able to understand the problems and is able to find solutions to it by the mental process.
