I highly recommend the following two books on mindfulness.
‘Get Some Headspace’ by Andy Puddicombe
“If you’ve ever wished you could quiet the chatter in your mind, focus more easily, experience an increased sense of calm and well being, or just get some sleep at night, then it’s time to get some headspace. There’s no chanting, no sitting cross-legged, and no need for any particular beliefs. What’s more, this easy to learn skill takes just 10 minutes a day, and can bring about life-changing results.” (Puddicombe, 2011)
“Meditation only works if you do it! It’s only when you sit down and do it on a regular basis that you’ll see any benefit. So while the practice of mindfulness can be applied any time, any place, anywhere, there’s no substitute for a daily meditation session. Those 10 minutes will give you the very best opportunity and conditions to become familiar with what it means to be aware. It’s also likely to provide you with a sense of stillness which is very difficult to replicate in everyday life when you first begin. So, whether you think of it as a an isolated exercise to get some headspace, the foundations for practising mindfulness throughout the day, or simply as a new hobby, the importance of sitting down to do it daily cannot be overstated.” (Puddicombe, 2011)
‘MindChi: Re-wire your Brain in 8 minutes a day’ by Richard Israel and Vanda North
“Just as Tai Chi has been used for centuries to balance body and mind, Mind Chi will help you to increase your mental energy and be more effective in everything you do. Mind Chi is a powerful synthesis of thought and action based on the most recent research into how the brain works. By following the simple, daily exercises you will raise your mental performance to a level you never thought possible.” (Israel & North, 2010)
“MindChi shows you how to build, manage and direct your mental energy for increased success and enjoyment in business and life. It allows you to adapt and reinvent yourself with superior performance in changing times. The concept of ‘Chi’ has its roots in chinese culture and philosophy and will be a familiar concept to anyone who has seen or practised t’ai chi … Chi is related to, but not precisely the same as, the scientific concept of energy. In Mind Chi the Chi energy is a feeling and an attitude related to your willpower. Your mental energy increases in line with your level of attention and strength of your intention. This is the basic premise of Mind Chi.” (Israel & North, 2010)
