PREFACE: "Yoga—that supreme bridge to cosmic attainment has existed through all ages. Each Teaching comprises its own Yoga, applicable to that step of evolution. The Yogas do not contradict each other. As the branches of one tree they spread their shade and refresh the traveler exhausted from heat.
His strength regained, the traveler continues on his way. He took naught that was not his, nor did he divert his striving. He embraced the manifested benevolence of space. He liberated the preordained forces. He mastered his single belonging.
Do not reject the forces of Yoga, but like light carry them into the twilight of labor unrealized.
For the future, we arise out of sleep. For the future, we renew our garments. For the future, we sustain ourselves. For the future, we strive in our thought. For the future, we gather strength.
First we shall apply the counsels of life. Then we shall pronounce the name of the Yoga of the time approaching. We shall hear the advancing footsteps of the element of fire, but we shall already be prepared to master the undulations of the flame.
Therefore, we hail the yoga of the past the Raja Yoga. And we affirm that of the future the Agni Yoga."
