Letter to a Friend by the great master Nagarjuna contains very practical advice and detailed instructions for all generations. It has been kept close to the heart and actualized by many practitioners across the centuries in India and Tibet. The main topic is how to be a good, decent, and responsible person in samsara. These principles are important and valuable for anyone, no matter where they live or what they believe. Dharma is based on cultivating a good character and ethical conduct combined with a deep understanding of interdependence. There is a profound relationship between one's mind, motivation, and how they interact with natural systems and human societies. Nagarjuna is inviting us to take a deeper look at this relationship, and the renowned master Mipham Rinpoche expands these points even further. Nagarjuna wrote this letter directly to his friend, but his advice applies to everyone. It explains how to be strong and conduct ourselves with courage and confidence in the world. It offers clear instructions on how to expand our human kindness and the precious qualities of morality, concentration, wisdom, and an open heart. We can work through difficult experiences and learn to meet all the challenges in samsara without a lot of hardship and struggle. Instead of collapsing and giving up, we can continue moving forward with good energy toward a bright future.
