Mutual happiness is rarely found in this material world. For one to win here, many have to lose. A true win-win situation is impossible in this world. Mutual happiness is only possible when a jiva connects with God. Then God becomes happy with his loving service and the devotee becomes happy with Krsna’s loving reciprocation. Ye yatha mam prapadyante…
There are only two categories of happy people in the material world: fools and transcendentalists. Fools are so oblivious that they manage to convince themselves that they are happy in this material prison. Transcendentalists are happy because they can see above the material dualities and know that their parole is at hand. Everyone else is essentially miserable. This is because calamity in the material world cannot be avoided, just as water cannot be avoided in the ocean.

Real Happiness is to love selflessly, being free of anger, lust & greed. In that state we can access the beauty, charm & mercy of the Supreme Lord.
Enduring difficulty for a meaningful purpose is a sublime pleasure.
Any person who is seriously desirous of achieving real happiness (Krishna Consciousness) must seek out a bona fide spiritual master and take shelter of him by initiation.
Spirit and matter are completely contradictory things. All of us are spiritual entities. We cannot have perfect happiness, which is our birthright, however much we may meddle with the affairs of mundane things. Perfect happiness can be ours only when we are restored to our natural state of spiritual existence.
