What Is Raja Yoga or Mental Development About?
This book is a short course on managing your own mind. The author, writing as Yogi Ramacharaka, begins with who you are, then moves to the tools of the mind, mental control, attention, and perception. He presents each step as a lesson to study and then practice, not just to admire.
The later lessons turn to the unfolding of consciousness, the levels of mind, and the work of the subconscious. The author teaches that you can direct these forces to build character and inner calm. As with all esoteric teaching, the claims are his, offered for you to test in daily life.

Lesson-by-Lesson Study Notes
These notes are our own summary, written to help you follow the book. Each one ends with a small practice you can try this week.
The “I”
The author begins with the self behind everything you think and feel. He teaches that you are not your body or your passing moods, but a conscious center he calls the Ego. He asks you to notice the one who is aware of your thoughts. This lesson sets the ground for all that follows, because control of the mind starts with knowing who is doing the controlling.
The Ego’s Mental Tools
Here the author describes the mind as a set of tools the Ego uses. He names several layers, including instinctive mind, intellect, and a higher spiritual faculty, and explains how each serves a different purpose. His point is that you are the user of these tools, not the tools themselves. Knowing what each one does helps you pick the right one for the task in front of you.
The Expansion of the Self
The author teaches that the sense of self is not fixed. It can grow outward as understanding widens, moving from a narrow focus on the body toward a larger awareness. He presents this growth as a natural unfolding that comes with study and practice. The lesson invites you to see yourself as more than your usual small picture and to expect your inner life to deepen.
Mental Control
This lesson is about taking charge of your own mind. The author argues that thoughts and feelings can be directed instead of simply endured, and that the Ego has the power to say what enters and what stays. He treats self-mastery as a skill built by repeated practice. The aim is a calm, steady inner life that does not get pushed around by every passing mood.
The Cultivation of Attention
The author presents attention as a faculty you can train, like a muscle. He teaches that where you place your attention shapes what you learn, remember, and become. He describes steady, willed focus as the doorway to nearly every other mental skill. Scattered attention, he suggests, wastes energy, while trained attention gathers it. The lesson encourages small, regular exercises in focus.
Cultivation of Perception
Perception, in the author’s view, is how the mind takes in the world, and most of us use it carelessly. He encourages sharper observation of what is around and within us. Looking closely, he says, feeds the mind with better material and improves memory and judgment. The lesson treats noticing as a learnable art that rewards patient, curious practice, especially when done with intention.
The Unfoldment of Consciousness
This lesson describes consciousness as something that unfolds in stages rather than switching on all at once. The author teaches that human awareness can rise to higher levels over time, and that this growth is part of our nature. He offers it as encouragement: the mind you have now is not the limit. Practice and patience, he says, let deeper awareness open naturally.
The Highlands and Lowlands of Mind
The author uses the image of high ground and low ground to describe the range of the mind. Lower thoughts, such as fear and base desire, sit in the lowlands, while higher thoughts, such as aspiration and wisdom, sit in the highlands. He teaches that you can choose where your mind lives. The lesson asks you to notice your usual territory and climb on purpose.
The Mental Planes
Here the author describes the mind as having planes, or levels of activity, from simple instinct up to refined spiritual thought. He explains that different kinds of mental work happen on different planes, and that we can learn to move between them. This is his map of the inner world. It helps a student understand why experiences differ and where to aim their growth.
Sub-consciousing
The author introduces the idea of handing work to the subconscious mind. He teaches that a question or task, held with clear intention, can be passed inward and answered later without strain. He compares this to how habits and skills become automatic. The lesson presents the subconscious as a quiet helper that works in the background when it is given good direction.
Subconscious Character Building
The author argues that character can be shaped by feeding the subconscious with chosen ideas. Repeated, positive suggestion becomes habit, and habit becomes part of who you are. He treats character as something built on purpose rather than inherited as fate. The lesson encourages careful choice of the thoughts you repeat, since he teaches that the subconscious absorbs them and acts on them.
Sub-Conscious Influences
The final lesson looks at the influences that reach us beneath awareness, including the thoughts and moods of other people and surroundings. The author teaches that we can become more watchful about what we absorb and can protect and direct our inner life. He closes the course with a call to responsibility: a student who understands these forces can choose which ones to welcome.

Frequently Asked Questions
What is Raja Yoga or Mental Development about?
It is a course of twelve lessons on training the mind. The author, writing as Yogi Ramacharaka, teaches that you can understand the self, direct your attention, and shape your character through mental discipline. It is a practical, step-by-step guide rather than a theory of philosophy.
Who wrote Raja Yoga or Mental Development, and when?
The book appeared in 1906 under the pen name Yogi Ramacharaka, which is attributed to the American writer William Walker Atkinson. It was issued by the Yogi Publication Society in Chicago. Atkinson lived from 1862 to 1932 and wrote many books under several names.
What kind of book is Raja Yoga or Mental Development?
It belongs to the early twentieth century New Thought and Western yoga tradition. The author borrows the Sanskrit term raja yoga and presents his own lessons on mind, will, and consciousness in plain English for Western readers. It is not a translation of an ancient Indian text.
How many lessons are in Raja Yoga or Mental Development?
There are twelve lessons. They begin with The “I” and The Ego’s Mental Tools, move through mental control, attention, and perception, then cover consciousness, the mental planes, and end with three lessons on the subconscious mind and its influences.
What does the author mean by the “I” in the first lesson?
The author uses “I” for the conscious Ego, the real self that stands behind the body and the mind. He teaches that knowing yourself as the user of your thoughts is the first step toward controlling them. The idea is the base for the later lessons.
How does the author teach mental control?
He teaches that the Ego can direct thoughts and feelings instead of being ruled by them. Control grows through steady practice, especially training of attention and will. The author presents it as a skill any patient student can build, not a gift for a few people.
What does the book say about the subconscious mind?
The last three lessons describe the subconscious as a helper that works below awareness. The author teaches that you can give it tasks, feed it chosen ideas to build character, and learn to notice the influences that reach you unseen. These are his claims, offered as practice.
How should a beginner read Raja Yoga or Mental Development?
Take it one lesson at a time and try the small practice that goes with each. The lessons build on each other, so read them in order. Pause often, and keep a short notebook of what you notice as you try the ideas.
Is Raja Yoga or Mental Development hard to read?
Not very. The style is clear and direct, though it uses some older terms and a few Sanskrit words. The author explains most of them as he goes. A beginner can follow it, especially with a guide that states each lesson in plain words.
How long does it take to finish Raja Yoga or Mental Development?
Most people can read or listen to the whole book in a few sittings, but the practices take longer. A twelve day plan, one lesson a day, is a gentle pace. Many readers return to the lessons several times over months.
How does this study guide and workbook help?
It gives a short, plain summary of each lesson, a simple practice to try, and a list of key ideas to keep close. The workbook pages let you write down what you notice, so the teaching moves from the page into daily life. The audiobook is available on Next Level Soul TV.
What should I read or listen to next?
Good next steps are other books on meditation, concentration, and the mind, or the author’s companion works on breath and inner development. You might also explore classic yoga texts and modern writing on attention. Choose whatever matches the practice you want to deepen.
