Yes, this Purusha consciousness must be maintained; otherwise the calm will not last. The knocks and blows that come from outside cannot disturb one, if this Purusha consciousness remains at the back.
On the top of the head is a Chakra - Sahasradala or the thousand-petalled lotus. There is a Chakra in the middle of the forehead between the eyebrows and one in the heart-centre. The region between the navel and head constitutes the mental field. From navel downward extending till the terminus of the spinal chord, mūlādhāra, is the seat of the vital.
Hinduism... gave itself no name, because it set itself no sectarian limits; it claimed no universal adhesion, asserted no sole infallible dogma, set up no single narrow path or gate of salvation; it was less a creed or cult than a continuously enlarging tradition of the Godward endeavour of the human spirit. An immense many-sided many-staged provision for a spiritual self-building and self-finding, it had some right to speak of itself by the only name it knew, the eternal religion, Sanatana Dharma.
All fanaticism is false, because it is a contradiction of the very nature of God and of Truth. Truth cannot be shut up in a single book, Bible or Veda or Koran, or in a single religion. The Divine Being is eternal and universal and infinite and cannot be the sole property of the Mussulmans or of the Semitic religions only, - those that happened to be in a line from the Bible and to have Jewish or Arabian prophets for their founders.
The mind is running on all sides to think about many things, - what we call thoughts coming from outside. We must withdraw the mind from these distractions and make it abide in the self. Thus guarding the peace within we shall have to do the work without.
The desire of your vital being is towards work. And the vital being won't find any interest in yoga so long as you do not have any experience of the higher and fuller life that is in yoga. As long as this experience is not there, the vital being will not find any interest.
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.
When I approached God at that time, I hardly had a living faith in Him. The agnostic was in me, the atheist was in me, the sceptic was in me and I was not absolutely sure that there was a God at all. I did not feel His presence. Yet something drew me to the truth of the Vedas, the truth of the Gita, the truth of the Hindu religion.
There should of course be left a field of work for the sake of experiment but at all times one must remember that there will always remain open a possibility of err.
Yoga is a generic name for any discipline by which one attempts to pass out of the limits of one's ordinary mental consciousness into a greater spiritual consciousness.
After having stopped the lower activities of the mind, it must be made receptive; and, instead of weaving all kinds of empty and idle thoughts, the mind should receive intuitions from above.
