Meditation depends upon the strength of mind. It must be unceasing even when one is engaged in work. Particular time for it is meant for novices.
Meditation helps concentration of the mind. Then the mind is free from thoughts and is in the meditated form.
There are no impediments to meditation. The very thought of such obstacles is the greatest impediment.
When there are thoughts, it is distraction: when there are no thoughts, it is meditation.
Meditation applies the brakes to the mind.
The master is within; meditation is meant to remove the ignorant idea that he is only outside. If he is a stranger whom you await, he is bound to disappear also. What is the use of a transient being like that? But so long as you think you are separate or that you are the body, an external master is also necessary and he will appear to have a body. When the wrong identification of oneself with the body ceases, the master will be found to be none other than the Self.
You may go on reading any number of books on Meditation. They can only tell you 'Realize the Self'. The Self cannot be found in books. You have to find it for yourself in yourself.
See what helps you to keep away all other thoughts and adopt that method for your meditation.
The main factor in meditation is to keep the mind active in its own pursuit without taking in external impressions or thinking of other matters.
Meditation is sticking to one thought. That single thought keeps away other thoughts; distraction of mind is a sign of its weakness; by constant meditation it gains strength.
Keep the remembrance of your real nature alive, even while working, and avoid haste which causes you to forget. Be deliberate. Practice meditation to still the mind and cause it to become aware of its true relationship to the Self which supports it. Do not imagine that it is you who are doing the work. Think that is the underlying current which is doing it. Identify yourself with the current.
Because truth is exceedingly subtle and serene, the bliss of the Self can manifest only in a mind rendered subtle and steady by assiduous meditation.
God dwells in you, as you, and you don't have to 'do' anything to be God-realized or Self-realized, it is already your true and natural state. Just drop all seeking, turn your attention inward, and sacrifice your ego mind to the One Self radiating in the Heart of your very being. For this to be your own presently lived experience, Self-Inquiry Meditation is a direct and immediate way.
