We must consider the role of diet, breath, the senses and our life-style not only in health but also in our spiritual practice. To merely talk or think about God without looking at how we live will not take us very far. Our food affects our mind and emotions in a profound way, calming or disturbing them. So good food is the first step to God. We should cleanse and nurture the mind with wholesome impressions born of nature and carrying Prana the trees, flowers, sky, clouds, mountains, lakes, rivers and oceans.
Good impressions are the second step to divinity.
Our associations affect our spiritual heart. Love is the only emotion that can be really digested. We should build our hearts with the association of spiritual people and seeking peace and happiness for all creatures and for the entire world. That is the basis of Satsanga or spiritual communion, which is the third step to consciousness. Your book mentions how we as individuals are reflections of the entire universe and mirror universal processes.
