The Grand Master Shiva X° (Ordo Templi Orientis, Grand Lodge of Australia) has previously written a blog post on the Living in the Sunlight practice, which should give you some insight into this practice.

From the back cover of the book

Living in the Sunlight by Steve King is a little gem of a book that is welcome and much needed, perhaps never as much as right now. Dedicated to the exposition of a deceptively simple meditation practice, the book’s clear and unassuming narrative is brimful with initiated knowledge, and steeped in the esoteric lore of Ordo Templi Orientis and Aleister Crowley’s Thelema. The practice of “Living in the Sunlight,” however, originates not with Crowley but with his “scarlet woman” Hilarion (Jeanne Robert Foster) and can be adopted by anyone, irrespective of denominational affiliations and ideological convictions. In essence, it is a method of identifying one’s deepest awareness with the Sun, for the ultimate purpose of radiating its light unto others. An antidote to the present culture of cynicism and ennui, Living in the Sunlight is based on a simple yet profound notion that happiness is contagious and grows by sharing. This book, and the method of putting it into practice, is rooted in a most radical idea, that the point of life is joy. Highly recommended.
