Raja = king; Yoga means King. Hnece King of all yogas is Rajayoga, meaning not only during meditation, but throughout the day you keep your soul as a ruler of your senses, mind and intellect.

It is easily accomplished! There are three tools to stay safe from the influence of the pressures of daily life, to survive and thrive and perhaps even to be a source of positive change in this 'mad' world. The first tool being the understanding that we are souls, points of luminous light, who have all the qualities of goodness with us and that everyone is just like me. When I come back to that awareness I come back to my original peaceful, loving and pure state of being that allows me to feel content and happy again. The second tool is that I, the soul am the creator of my thoughts and that the intellect with knowledge of the original nature of the soul can guide the mind back to peace and, by staying aware of this, can transform negative personality traits by applying this knowledge in practice. This then allows the soul to remove the dust of negativity and come back to truth and wisdom. The third tool shared was the knowledge of the Supreme, being just like us a point of light who is ever pure, peaceful, loving, blissful & powerful, who is constant and the Father of all souls and by connecting again and again to that One, making Him my Friend.

Supergirl, I was so happy to read your question because I am reading the same book and loving it so much. There is a lot of info about yoga and about the book and author on the website www.yogananda-srf.org I ordered another of his books so that I can continue being inspired after I am done with the autobiography. Best wishes!
