A yogi who perceives his real Self as separate from his active senses and their objects never becomes attached to anything. He is aware of the dream nature of the universe and watches it without being entangled in its complex but ephemeral nature.
If a householder moulds himself according to the circumstances - just like nature moulds itself according to seasons - and performs his karma, then only shall he acquire happiness. One who does this successfully gains in all walks of life.
That which gives pleasure to one man gives pain to another. That sage who identifies himself with the imperishable Self and stands as a spectator of the mental modifications enjoys supreme peace and infinite bliss.
When we see everything in life as a game, we will be equally joyous when falling as we are when rising. If we can fully understand this – if we can see life as swinging on a swing – we will never fall apart when failure comes our way.
