In 1950 Krishnamurti said: It is only when the mind is not escaping in any form that it is possible to be in direct communion with that thing we call lonliness, the alone, and to have communion with that thing, there must be affection, there must be love. On Love and Lonliness is a compelling investigation of our intimate relationships with ourselves, others, and society. Krishnamurti suggests that true relationship can come into being only when there is self-knowledge of the conditions which divide and islolate individuals and groups. Only by renouncing the self can we understand the problem of lonliness, and truly love.

After decades of service and years of watching her family's troubles splashed across the tabloids, Britain's Queen is beginning to feel her age. She needs some proper cheering up. An unexpected opportunity offers her relief: an impromptu visit to a place that holds happy memories—the former royal yacht, Britannia, now moored near Edinburgh. Hidden beneath a skull-emblazoned hoodie, the limber Elizabeth (thank goodness for yoga) walks out of Buckingham Palace into the freedom of a rainy London day and heads for King's Cross to catch a train to Scotland. But a characterful cast of royal attendants has discovered her missing. In uneasy alliance a lady-in-waiting, a butler, an equerry, a girl from the stables, a dresser, and a clerk from the shop that supplies Her Majesty's cheese set out to find her and bring her back before her absence becomes a national scandal.Mrs Queen Takes the Train is a clever novel, offering a fresh look at a woman who wonders if she, like Britannia herself, has, too, become a relic of the past. William Kuhn paints a charming yet biting portrait of British social, political, and generational rivalries—between upstairs and downstairs, the monarchy and the government, the old and the young.

Jenna Miscavige Hill was raised to obey. As the niece of the Church of Scientology leader David Miscavige, she grew up at the center of this highly controversial and powerful organization. But at twenty-one, Jenna made a daring break, risking everything she had ever known and loved to leave Scientology once and for all. Now she speaks out about her life, the Church, and her dramatic escape, going deep inside a religion that, for decades, has been the subject of fierce debate and speculation worldwide. Piercing the veil of secrecy that has long shrouded the world of Scientology, this insider reveals unprecedented firsthand knowledge of the religion, its obscure rituals, and its mysterious leader David Miscavige. From her prolonged separation from her parents as a small child to being indoctrinated to serve the greater good of the Church, from her lack of personal freedoms to the organization emphasis on celebrity recruitment, Jenna goes behind the scenes of Scientology oppressive and alienating culture, detailing an environment rooted in control in which the most devoted followers often face the harshest punishments when they fall out of line. Addressing some of the Church most notorious practices in startling detail, she also describes a childhood of isolation and neglect a childhood that, painful as it was, prepared her for a tough life in the Church most devoted order, the Sea Org. Despite this hardship, it is only when her family approaches dissolution and her world begins to unravel that she is finally able to see the patterns of stifling conformity and psychological control that have ruled her life. Faced with a heartbreaking choice, she mounts a courageous escape, but not before being put through the ultimate test of family, faith, and love. At once captivating and disturbing, Beyond Belief is an eye-opening exploration of the limits of religion and the lengths to which one woman went to break free.
