The Bhagavad-gita (02.66)(02.67) indicates that when we let ourselves forget Krishna, we lose access to the inner happiness that comes from remembering him. Consequently, our need for happiness makes us vulnerable to the winds of passing material desires, which disorient our mind and intelligence. We oscillate between various desire-winds and end up being carried away by whichever desire-wind happens to be blowing the strongest at that moment (read “the current fashion”). However, as all material pleasures are temporary, they soon leave us feeling empty and dissatisfied. To remedy this dissatisfaction we keep attempting to get newer external pleasures (read “the new fashion”). As all such pleasures are temporary, all our attempts simply add new chapters in our history of dissatisfaction.

The only way to end the dissatisfaction is by tackling its root: the disconnection from Krishna. When we determinedly re-connect ourselves with Krishna by cultivating his prayerful remembrance, that devotional connection finally provides us the happiness that we have always been longing for. 

Bhagavad Gita Chapter 02, Text 66

“One who is not connected with the Supreme [in Krishna consciousness] can have neither transcendental intelligence nor a steady mind, without which there is no possibility of peace. And how can there be any happiness without peace?”
