The "I" thought is said to be the sum total of all thoughts. The source of the "I" thought has to be inquired into.

Every living being longs always to be happy, untainted by sorrow; and everyone has the greatest love for himself, which is solely due to the fact that happiness is his real nature. Hence, in order to realize that inherent and untainted happiness, which indeed he daily experiences when the mind is subdued in deep sleep, it is essential that he should know himself. For obtaining such knowledge the inquiry 'Who am I?' in quest of the Self is the best means.

When the mind, one-pointed and fully focused, knows the supreme silence in the Heart, this is true learning.

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.

Calmness is the criterion of spiritual progress. Plunge the purified mind into the Heart. Then the work is over.

The place where even the slightest trace of the 'I' does not exist, alone is Self.

To know one's Self is to be blissful always.
