Based on Bhagavad Gita Chapter 06, Text 32
When external problems trouble us, we may feel that they need to be solved first, and so we can’t afford time for our inner life. Paradoxically, Gita wisdom suggests that we need our inner life the most during such troubling times. Let’s see why.
The sixth chapter of the Bhagavad-gita states that the greatest yogis retreat deep within the innermost recesses of their hearts. There, they experience the highest happiness that comes by re-establishing their personal devotional connection with Krishna, the supreme reservoir of all happiness and the equal spiritual potential of all living beings as integral parts of the supreme (06.32). Such experiences convince them that everyone has the capacity and deserves the opportunity to relish the sublime joy that they have relished. Not only that, they recognize that this inner fulfilment is the greatest necessity of those facing outer turbulence.
Because they have understood through their personal experience that external stability is difficult to attain or sustain without internal serenity.
