Buddhism is the story of a man’s spiritual journey to Enlightenment, and of the teachings and ways of living that developed from it.
A mental image of the Buddha is recommended as the focus of attention in the development of single pointed concentration – a quote by Kathleen McDonald.
Various devotional practices of Buddhism involve visualisation such as visualising offerings of delightful objects to the Buddha, just looking at a Buddha brings calm and tranquility to your mind and home.
