This quote emphasizes the value of embracing a humble, simple lifestyle. It suggests that adopting a less complicated way of life does not make one’s life less valuable or fulfilling, but rather, it enriches it. The ‘simpler self’ refers to a state of being where material possessions and social status are not the primary focus. Instead, one’s attention is directed towards self-awareness, self-improvement, and spiritual growth.

When Rumi says ‘humble living does not diminish, it fills,’ he is implying that living modestly, away from the distractions and excesses of a materialistic life, can lead to a sense of fulfillment. This sense of fulfillment comes from the clarity, peace, and wisdom that one attains when they focus less on external validation and more on their internal state of being.

The second part of the quote, ‘going back to a simpler self gives wisdom,’ suggests that reverting to a less complicated, more authentic version of oneself leads to wisdom. This wisdom is not acquired through intellectual pursuits but through the introspection and self-awareness that comes with leading a simple, humble life.

In today’s fast-paced, consumer-driven society, this quote is particularly relevant. Many people are constantly in pursuit of more – more money, more possessions, more recognition, but this endless pursuit often leads to stress, dissatisfaction, and a sense of emptiness.

Applying this quote to personal development could mean focusing less on materialistic goals and more on personal growth and self-improvement. It could mean spending less time chasing after societal standards of success and more time cultivating self-awareness, compassion, and gratitude. It could also mean simplifying one’s lifestyle – decluttering one’s living space, reducing consumption, and focusing on the essentials. By doing so, one can create space for introspection, self-discovery, and ultimately, wisdom.
