Vedanta declares that happiness is not the goal of life. Wisdom is the goal of life.
Swami Vivekananda says, “Sense-happiness is not the goal of humanity. Wisdom (Jnana) is the goal of all life. We find that man enjoys his intellect more than an animal enjoys its senses; and we see that man enjoys his spiritual nature even more than his rational nature. So, the highest wisdom must be this spiritual knowledge. With this knowledge will come bliss. All these things of this world are but the shadows, the manifestations in the third or fourth degree of the real Knowledge and Bliss.” (The Complete Works of Swami Vivekananda. 3:4)
If we understand this, then everything in the world and our own life starts making sense. The dualities like success-failure, fame-disgrace, wealth-poverty, health-disease, and pleasure pain, keep alternating. This whole scheme, when understood correctly, makes us wiser. Through this wisdom, we go beyond the dualities. The dualities no longer affect us. We are ever peaceful and blissful. This is the goal.
