Raja Yoga, also spelled Rajayogam the "royal path," is a system of yoga focused on controlling the mind through meditation and self-discipline, often following Patanjali's Eight Limbs (Ashtanga Yoga) to achieve mental stillness and spiritual realization, though "Rajayogam" can also refer to powerful, auspicious planetary combinations in Vedic astrology that promise success and wealth. The yoga path involves Yama (ethics), Niyama (observances), Asana (postures), Pranayama (breath), Pratyahara (sense withdrawal), Dharana (concentration), Dhyana (meditation), and Samadhi (bliss). Raja Yoga (The Path of Yoga) Core Principle: To still the mind's "thought-waves" to reveal the divine Self within, leading to ultimate consciousness

The core principle of Raja Yoga is to still the mind's thought-waves to reveal the divine Self within, leading to ultimate consciousness. Meditation helps control thoughts and attain inner peace.

Rajayogam in Vedic astrology refers to powerful planetary combinations that bring success, wealth, and leadership. While Raja Yoga focuses on spiritual realization, Rajayogam refers to worldly success.

Modern transportation provides trains, airplanes, and ships. Yogins claim that through Yogic powers they can travel instantly through space, gain knowledge of distant events, and hear sounds from afar through mental projection.

Yogins develop Siddhis through concentration and Sadhana. Pranayama is one of the most important practices. Asana controls the physical body, and Pranayama controls the subtle astral body.

Pranayama is essential in daily spiritual practices. It is performed before eating, drinking, or undertaking any task, ensuring success and mental clarity.

The power of concentration allows Yogins to demonstrate extraordinary memory and perception abilities. These abilities develop through daily Pranayama practice.

Prana is the vital life force responsible for motion, thought, and activity. Pranayama means control of this vital energy. Control of Prana leads to mastery over body, mind, and nature.

According to Hindu philosophy, the universe consists of Akasa (matter) and Prana (energy). All physical and mental forces originate from Prana.

Today, for quick travel, the material world presents us the Railway, Steamers, Aeroplanes and so fourth, but the Yogins claim that by Yogic culture the weight of the body can be so reduced that it can fly over the space to any distance in an instant. They can prepare a magic ointment, which when applied to the soles of the feet, gives them power to traverse any distance on earth within a very short time. By the practice of Raja Yoga with different kriya , by applying the elongated tongue to the posterior nasal openings they can fly in the air. By keeping a magic pill in their mouth they can also move in space to any place in the twinkling of an eye. When we are anxious to know the welfare of our own relations in a distant or foreign land, we take recourse to writing letters sending ordinary or urgent cables. But the Yogins claim that they can, by meditation (Dhyana), know anything that happens in other parts of the world by a projection of the mind or by mentally travelling the distance which is only a matter of a few seconds. Yogi Lahiri, whose Samadhi is still in Varanasi, travelled to London to see the state of health of his superior’s wife. For hearing a friend at long distance the material world presents us with telephones and wireless receivers, but the Yogins claim that through their Yogic power, they can hear anything, from any distance, even the voices of God and other invisible beings in the firmament. Today when a man is suffering from a disease the material world presents us with doctors, medicines, injections and so forth, but the Yogins claim that the by a mere glance or by simple touch or by recitation of Mantras, not only the diseases can be cured but also life can be given to a dead man.

These Yogins by persistent effort in concentration get different Yogic powers that are known as “Siddhis.” Those who acquire these Siddhis, are known as Siddhas. The process, through which they obtain Siddhis, is called Sadhana. Pranayama is one of the most important Sadhanas. Through the practice of Asana, you can control the physical body and through Pranayama, you can control the subtle, astral body or the Linga Sarira. As there is an intimate connection between the breath and nerve-currents, control of breath leads to the control of vital inner currents.

Through sincere practice of Yoga and Pranayama, infinite knowledge, bliss, peace, and power can be attained.

Before he eats, before he drinks, before he resolves to do anything, Pranayama should be performed first and then the nature of his determination should be clearly enunciated and placed before the mind. The facts of its preceding every effort of the will is a surety that, that effort will be crowned with success and the mind be directed to bring about the desired result. Here I may refer to the feat of memory, practised by the Hindu Yogins, under the name of concentration on one hundred questions are put to a Satavadhani or the concentrator in rapid succession by different persons; some testing the verbal memory of the performer; others testing his power of mental calculation; again some others, trying to test his artistic skill, without giving him, any time for committing the questions to have been put to him, the performer begins, by reproducing the questions, in any order, in respect to those questions, with their answers. This is generally done in three or more turns, in each of the questions and then continuing from where he left off in the next turn. If the questions are of the nature of mathematical problems whose solutions are required, he delivers the answers along with the problems, having solved them mentally.
The Prana may be defined as the finest vital force in everything which becomes visible on the physical plane as motion and action and on the mental place as thought. The word Pranayama, therefore, means the restraint of vital energies. It is the control of vital energy which tingles through the nerves of persons. It moves his muscles and causes him to sense the external world and think his internal thought. This energy is of such a nature that it may be called the vis viva of the animal organism. The control of this force is what is aimed at by the Yogins by means of Pranayama. He, who conquers this, is not only the conqueror of his own existence on the physical and mental plane, but the conqueror of the whole universe into its present form and which is pushing it towards its ultimate goal. To the Yogi the whole universe is his body. The matter which composes his body is the same that evolved the universe. The force which pulsates through his nerves is not different from the force which vibrates through the universe. The conquest over the body does, therefore, mean to him the conquest over the forces of nature. According to the Hindu Philosophy the whole nature is composed of two principal substances. One of them is called the Akasa or ether and the other, Prana or energy. These two may be said to correspond to matter and force of the modern scientists. Everything in this universe that possesses form omnipresent and solid, the whole universe, consisting of our solar system and millions of huge systems like ours and in fact every kind of existence that may be brought under the word ‘created,’ are the products of this one subtle and invisible Akasa and at the end of each cycle return to the starting point. In the same way, all the way of forces of nature that are known to man; gravitation, light, heat, electricity, magnetism all those that can be grouped under the generic name of ‘energy’ physical creation, nerve-currents, all such as are known as animal forces and thought and other intellectual forces also, may be said to be the manifestations of the cosmic Prana. From Prana, they spring into existence and in Prana, they finally subside. Every kind of force in this universe, physical or mental, can be resolved into this original force. There can be nothing new expect these two factors in some one of their forms. Conservation of matter and conservation of energy are the two fundamental laws of nature.
