The navel region is the centre of the vital. It is from here that the movements of the vital rise upward. Above the navel and behind the chest is the centre of the play of emotions and below this takes place the play of the physical. Mulādhāra is the base of the physical. In between the Mulādhāra and the navel, there is another centre of the vital.
There is the physical mind which is mechanical but the awareness which is the essential character (dharma) of the mind is also to some extent present there.
There are four great events in history, the siege of Troy, the life and crucifixion of Christ, the exile of Krishna in Brindaban and the colloquy on the field of Kurukshetra. The siege of Troy created Hellas, the exile in Brindaban created devotional religion, (for before there was only meditation and worship), Christ from his cross humanized Europe, the colloquy at Kurukshetra will yet liberate humanity.
The yoga we practice is not for ourselves alone, but for the Divine; its aim is to work out the will of the Divine in the world, to effect a spiritual transformation and to bring down a divine nature and a divine life into the mental, vital and physical nature and life of humanity. Its object is not personal Mukti, although Mukti is a necessary condition of the yoga, but the liberation and transformation of the human being. It is not personal Ananda, but the bringing down of the divine Ananda - Christ's kingdom of heaven, our Satyayuga - upon the earth.
Samskrit language, as has been universally recognized by those competent to form a judgment, is one of the most magnificent, the most perfect, the most prominent and wonderfully sufficient literary instrument developed by the human mind.
Evolution is not finished; reason is not the last word nor the reasoning animal the supreme figure of Nature. As man emerged out of the animal, so out of man the superman emerges.
What do you want to do sadhana for? The aim should not be the satisfaction of egoism: "I want to be a great yogi; I shall have so much power and with that power I shall establish myself in the world." All such thoughts must be thrown far away.
The Bhagavad-Gita is a true scripture of the human race a living creation rather than a book, with a new message for every age and a new meaning for every civilization.
Even if the being is not entirely purified, varieties of inspirations and powers may come down from above but this may lead to serious errors. Inspirations from above mixing with the impurities from below get all muddled up and the sadhak takes this for an absolute command. Many a sadhak has thus fallen into danger. Therefore, one must particularly lay stress on the purification of the being.
The first and the most important thing is to know that life is one and immortal. Only the forms, countless in number, are transient and brittle. The life everlasting is independent of any form but manifests itself in all forms. Life then does not die... but the forms are dissolved.
