Sense perception is the cause of feeling all sorts of happiness and distress. Form, taste, odor, sound, and touch are different sense perceptions, which render happiness or distress in cooperation with the mind. In winter, bathing in cold water gives us pain, but in summer, the same cold water gives us pleasure. In winter, fire gives us pleasure and warmth, but in summer, the same fire gives us distress. Thus, neither fire nor water has any intrinsic power to give us happiness or distress, but they appear to us as agents of happiness or distress, according to our mode of sense perception in various circumstances. Therefore, everything that exists in the world is neither an object of happiness nor an object of distress; everything is simply subjective—that is, subject to our sense perceptions as they relate to our processes of thinking, feeling, and willing.
But such temporary sensations of happiness and distress, pertaining to the act of thinking, feeling, and willing under a false ego, are eternally different from the spirit soul and are therefore "unreal reality." Whatever advancement of knowledge, whether in art or science, that has been made by mundane scholars without reference to the eternal spirit soul is but a manifestation of the illusory modes of nature that encompass and limit the material body and mind.
Real peace and happiness can never come about through such advanced materialistic knowledge, deluded as it must be by the illusory modes of nature with a view to playing up this "unreal reality." Rather, as Śrī Kṛṣṇa, the Personality of Godhead, confirms in the Bhagavad-gītā, only those who cultivate transcendental knowledge in relation to the eternal spirit soul and without being disturbed by temporary happiness and distress will be able to escape the cruel hands of birth, death, old age, and disease and will be truly happy by gaining eternal, spiritual life.
We therefore suggest that all those who have tried their utmost to do good for others but have failed despite all honest endeavors should approach Śrī Kṛṣṇa or His bona fide servitors, following the footsteps of Marshal Arjuna. One should try to do good for others, but only after knowing perfectly how to do good for others. Otherwise, if one embraces others in a false sense of altruism, one can get only a temporary benefit for himself in the shape of some profit, adoration, or distinction.
