What does the concept of Brotherhood mean? What kind of relationships are needed between people to create a single family of humanity? Based on love and trust, Brotherhood is the ideal human relationship. Although it may seem unattainable in our present world, since ancient times, the Great Brotherhood of Teachers has been an embodiment of high concord between people on our planet. Its Brothers and Sisters have worked tirelessly for the common good and self-sacrificially shared all the burdens of the world with humanity. In Book 9 of The Teaching of the Heart series, the Lord of Love and Compassion invites you to look at the harmony that reigns between the Elder Brothers and Sisters of humanity. He will tell you about the tasks set before the Great Brotherhood in the 21st century and how to overcome the obstacles that all people face on the way to the creation of Universal Brotherhood on the Earth. The ethical principles of Brotherhood outlined in this book will help you apply them in your relationships with people around you, following the example of the Teachers of humanity. After all, peace on the Earth will be established only when everyone sees a brother or a sister in every neighbour, regardless of race, gender, colour, religion, social origin, or other differences.
