The distinction between "being" and "becoming" is a philosophical concept often discussed in the realm of mindfulness, personal growth, and psychology.

"Being" refers to a state of acceptance and contentment with the present moment. It is about recognizing and appreciating what you have right now, rather than focusing on what you lack or what you wish to achieve. In the context of happiness, "being" is about finding joy in the current state of affairs, irrespective of external circumstances.

On the other hand, "becoming" refers to the constant pursuit of growth, improvement, and future goals. It's about the drive to achieve more, to grow, and to continuously evolve. This pursuit can be rewarding, as it often leads to personal development, achievement, and progress. However, an overemphasis on "becoming" can also lead to perpetual dissatisfaction, as one might never feel content with their present state.

In the context of mindfulness, the challenge lies in balancing "being" and "becoming." It's important to strive for growth and improvement (becoming), but equally important to appreciate the present moment and be content with what you have (being). This balance can help cultivate a sense of fulfillment and well-being, and prevent feelings of constant lack or dissatisfaction.

Non-Dual Mindfulness (NDM) is a practice that integrates the wisdom of various philosophical and spiritual traditions, focusing on the experience of the present moment without the separation of observer and observed. In the context of "being" and "becoming," NDM encourages a deep sense of "being."

In NDM, the practice is to be fully present and aware, letting go of the dualistic mindset that categorizes, compares, and strives for something different or better. There's an emphasis on "being" rather than "becoming."

However, it doesn't imply a rejection of growth or transformation. Instead, it suggests that true transformation arises naturally out of a deep acceptance and understanding of the present moment, rather than from striving or seeking. Therefore, "becoming" in the context of NDM is more of a natural evolution that arises from the depth of "being."

So, while traditional models of personal growth may put more emphasis on "becoming," in NDM the primary focus is on "being," with "becoming" seen as a natural outcome of deeply inhabiting the present moment.
