Do not worry because you cannot follow the course exactly to the letter. Do what you can of it, adapt it to your life, and do the best you can in present circumstances. The principal thing is to get twice daily into what is called the Silence, to quieten the senses, and get in touch with the Unseen, i.e., God, Divine Mind, the Infinite, Principle of Good, First Cause, the Absolute, the name does not matter, they all mean the same. another vital thing is to use affirmations and denials, these will be explained more fully later. Yet another is meditation, for you gradually grow into the likeness of that upon which you meditate.
