Even if there is a realm beyond mortality, would finding it improve our lives on earthWhat use is Spirit to a troubled worldDo prayer and meditation workAs a young man in search of love and a purpose to live for, the author could not fit within the world he found. Longing to be useful but unwilling to conform, he went out to South America. It wasn’t so easy. Alone on a mountainside one day, an inner voice said, ‘To make whole, be whole’. This was a turning point. He realised that, before being able to help others, he first had to work on himself. Once back in England, he found a method of meditation. Love of nature led him to become one of the first organic farmers but, when asked what he really wanted in life, he answered ‘God’. He’d been schooled in the Christian faith but was not at this time attracted to the Church. Meditation proved an ideal accompaniment as further adventures took him to Africa and, in particular, the desert. Later, at a low ebb in the USA, he ‘met Jesus’, which brought his practice of meditation and Christianity together. At the age of 51, he re-entered university to study Russian prior to visiting his mother’s homeland for the first time in 1991. This led to several years living in Russia, where he realised the similarity between his own practice and traditional Orthodox ‘prayer of the heart’. The book is based on notes of the author’s unfolding spiritual experience, which taught him that the wholeness he sought is actually – Spirit. How is it attainedWith many encouraging examples he shows how, with patient perseverance, the grip of the ego with all the restrictive unhappiness it brings, can be released. Being then more open to the influence of Grace, we may come to discover the Kingdom of God – our original, spiritual and perfect home. Dear John, ‘I hope you won’t mind my addressing you by your Christian name but having read your book twice as well as highlighting many paragraphs to study, I feel you are a dear friend. I am writing to say that your profound insights are enormously encouraging, an awakening, a wonderful inspiration for me, and I feel so fortunate to have found them. Your experiences in Spirit are conveyed so clearly and simply ‘ I find them truly uplifting. Every day I read some pages and always seem to find something new. I feel extremely grateful that you chose to write of your experience ‘ your legacy is to inspire countless other people, and to enrich their lives as you have mine.’ ML, 2011 Dear Mr Butler, ‘I am over half-way through your book ‘Wonders of Spiritual Unfoldment’ and feel I would like to express my gratitude to you for helping me gain clarity in the process of awakening. It is difficult to express in words the way your writings from personal experience have helped crystallise my sense of ‘Being’ in Reality. Your notes on waking from the dream or illusion we mistake for life and the sense of non-attachment to the world this engenders ‘ greatly assist me in releasing my conditioned perception. It is wonderful to find that someone living so near me, geographically, can write with such clarity and, knowing that you are here in the flesh confirming the truth of the possibility of waking up, has been a great affirmation to me and is supporting me in my own journey of awaking or coming home. Thank you so much.’ L, 2011 ‘This is a moving, honest ‘ and long ‘ spiritual autobiography, interestingly given in two voices: contemporary notebooks interlaced with present day ruminations. Butler met the meditation early and it colours his early days of self-sustaining farming after Cambridge, and his many adventures described in detail and with compassion in South America, Africa (sharing keenness of hunger and the haunting splendour of the night skies) and India, culminating in coming ‘home’ to his core way in the Russia of his mother and its Christian orthodoxy. It was love that led him through the labyrinth of his life ‘ a path we all recognise. As he says, ‘to surrender myself and let the spirit act.’ Throughout it is his honesty which makes the book valid for us. His spiritual insights have all been gained through the experience of this varied life which he seems to have accepted with the innocence and enthusiasm of a child. His way is our way. It is a book of vivid de*ion and some very helpful insights.’ Contact 55 – Summer 2011

Handsome, noble Lord Alistair McDonon’s gay life, as a denizen of London’s Beau Monde far, far away from his Scottish roots, comes to a sudden and abrupt end. When the tragic news arrives that his two brothers have drowned at sea, he is summoned to Scotland by his estranged father not only to take up his title of the Marquis of Kildonon and position of heir to the Chieftainship of the Clan but also to marry, Lady Morag McNain, in order to unite their Clans, who have been at war with each other for centuries. Horrified, Lord Alistair hastily proposes to his current lover, Olive Beverley – only to be refused and it seems that he is doomed to a loveless marriage in the windswept and distant Highlands. Suddenly, though, everything changes when he overhears a delicately beautiful young woman, called Arina, desperately begging the heartless Olive for enough money to pay for her beloved mother’s life-saving operation. Alistair steps in to help Arina, asking in return only that she accompany him to Kildonon Castle pretending to be his wife. So now no one can force him to marry Lady Morag – but little does Lord Alistair know that his demure ‘young pretender’ will soon be laying an irrevocable claim to his heart!

When her father, the Grand Duke, tells the lovely young Princess Tora of Radoslav that she is to marry the aged King of Salona, she is appalled and horrified. But no amount of pleading by her will change her father's mind. So Tora decides that she must find a way to see her prospective husband without his being aware of her presence and then try to find a way to escape her awful Fate. Since she is a talented musician, she has little difficulty in persuading her dear friend, Professor Lazar Srejovic, the nation's greatest musician, to allow her to join his famous quartet for a concert at the King of Salona's Palace. She devises a cunning plan to escape from the Palace of Radoslav, so that her father cannot stop her and joins up secretly with the Professor's quartet to travel by carriage to Maglic, the Capital of Salona. But on arriving at an inn on the way disguised in peasant dress, she is terrified to unexpectantly overhear a sinister plot to murder and violently overthrow the King of Salona and seize his country by force. Her life is now in danger, but, when a dashing and handsome stranger comes to her rescue when she is hiding in a wood near the inn, she loses her heart to him utterly in a moment and just as quickly loses all hope that they can ever be together. And her future is sealed for ever with no hope of love and happiness.

Bereft and penniless after the death of their father, the local Vicar and Private Chaplain to the Earl of Chadwood, the beautiful Olivia Lambrick, her younger brother Tony and her five-year-old sister Wendy are desperate for the new Earl to arrive at Chad Hall. Having inherited the title after his two cousins drowned in a sailing accident, it has taken the Earl a year to travel home from India. And meanwhile, with no one to pay the estate’s workers and pensioners, the entire village is almost starving. Olivia hopes that the Earl will honour the allowance her mother received as the late Earl’s cousin, but to her chagrin, he is a handsome but hard and unsympathetic man. Refusing Olivia’s pleas and those of his half-brother, Gerald, who faces the debtors’ prison because of his high living in London, the Earl has a very unpleasant solution – he will pay Gerald’s debts only if he marries Olivia! But Fate intervenes unexpectedly when the Earl is attacked by a vicious mob of youths from the village and, almost fatally injured by a knife thrust, is then carried to Olivia’s home. While Gerald uses a Power of Attorney to save the village, pay off his debts and look after the pensioners, Olivia saves the life of the man she hates and prays with all her heart that somehow love will save the day.
