Happiness is your real nature. You identify with yourself with the body and mind, feel its limitations, and suffer. Realize your true self in order to open the store of happiness. That true self is the reality, the Supreme Truth, which is the self of all the world you now see, the self of all the selves, the One real, the Supreme, the Eternal self - as distinct from the ego or the bodily idea for the self.
The world is so unhappy because it is ignorant of the true Self. Man’s real nature is happiness. Happiness is inborn in the true Self. Man’s search for happiness is an unconscious search for his true Self. The true Self is imperishable; therefore, when a man finds it, he finds a happiness which does not come to an end.
Happiness is not to be sought in solitude or in busy centers. It is in the Self.
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.
Pleasure and pain are only aspects of the mind. Our essential nature is happiness.
The explorers seek happiness in finding curiosities, discovering new lands and undergoing risks in adventures. They are thrilling. But where is pleasure found? Only within. Pleasure is not to be sought in the external world.
Unless one is happy, one cannot bestow happiness on others.
Concentration is not thinking of one thing. On the contrary, it is excluding all thoughts, since all thoughts obstruct the sense of one's true being. All efforts are to be directed simply to removing the veil of ignorance. Concentrating the mind solely on the Self will lead to happiness or bliss. Drawing in the thoughts, restraining them and preventing them from straying outwards is called detachment (vairagya). Fixing them in the Self is spiritual practice (sadhana). Concentrating on the heart is the same as concentrating on the Self. Heart is another name for Self.
One must realise his Self in order to open the store of unalloyed happiness.
Nearly all mankind is more or less unhappy because nearly all do not know the true Self. Real happiness abides in Self-knowledge alone. All else is fleeting. To know one's Self is to be blissful always.
Such happiness is relative and is better called pleasure or satisfaction.
Willpower should be understood to be the strength of the mind, which makes it capable of meeting success or failure with equanimity. It is not synonymous with certain success. Why should one's attempts always be attended by success? Success breeds arrogance and man's spiritual progress is thus arrested. Failure, on the other hand, is beneficial, inasmuch as it opens his eyes to his limitations and prepares him to surrender himself. Self surrender is synonymous with eternal happiness.
Happiness is your nature. It is not wrong to desire it. What is wrong is seeking it outside when it is inside.
