This quote asserts that the practices of Buddhism, like meditation, are not exclusive to those who follow the religion. They are universal techniques that anyone, regardless of their beliefs or backgrounds, can incorporate into their lives.

Meditation, for instance, is a method of training the mind similar to how fitness is an approach to training the body. It involves techniques to promote relaxation, build internal energy, and develop compassion, love, patience, generosity, and forgiveness. It’s a means to understand the content and workings of our own mind, to gain mastery over our thoughts and feelings, rather than being their slave.

Applying this to the contemporary world, we live in an era characterized by busyness and constant distraction. Stress, anxiety, and mental health issues are prevalent. In such a scenario, the adoption of Buddhist techniques like meditation can be a potent tool for personal development and mental well-being.

Meditation can help us to cultivate mindfulness, the practice of purposely focusing your attention on the present moment—and accepting it without judgment. This can lead to reduced stress and improved mental clarity and focus. Mindfulness can help us to react to stress or difficulties more calmly, choose how we respond to our own thoughts, and be more fully present in each moment of our lives.

In a broader societal context, if more people adopted techniques like meditation, it could potentially lead to a more peaceful, understanding, and compassionate society. It’s about fostering a culture of introspection and self-improvement that transcends religious boundaries.

In conclusion, the essence of this quote is that the tools for personal growth and mental peace are available to everyone, regardless of their religious or philosophical beliefs. It invites us to explore and adopt practices like meditation, not as a religious obligation, but as a universally accessible means to improve our life.
