Letting go is often one of the most challenging experiences we go through in life, but it's also an essential part of our growth and transformation. It's wonderful that you're reaching out on behalf of your grandson, Bradley.

Firstly, it's important to know that it's okay to feel pain and grief when letting go of a friend. As I wrote in "Real Love," every time we cry, we should cry our heart out - that's how we get the best release. By allowing ourselves to fully feel these emotions, we can move past them rather than being held captive by them.

Moreover, letting go doesn't mean forgetting or negating the friendship's value. It's about recognizing that this relationship has served its purpose in his life and accepting that life is taking him and the friend in different directions now.

Bradley might find it helpful to practice meditation focused on acceptance and letting go. He could use phrases like, "May we both find peace", or "May we both live with ease", sending loving-kindness to himself and his friend. This can be a gentle way to accept the situation without trying to fix or change it.

Most importantly, remember to extend kindness and compassion towards himself during this process. It's a difficult transition, and it's okay to not have it all figured out right away. We need to be patient with ourselves during these times.

Also, he can consider journaling as a way to express his feelings and thoughts. This can grant him clarity and help him navigate this transition.

Remind Bradley to stay open to the new possibilities that are awaiting him. To quote Alice Walker, "Even as I hold you / I am letting go"; each end signifies a new beginning. Remember, every experience is an opportunity for growth and learning.
