Bhagawan explains beautifully the meaning of the Gayathri Manthra :
In the Gayathri Manthra the first line is: "Om Bhur bhuvas suvah." This manthra is assumed to refer to three worlds, the earth, the middle world and Heaven--Svarga, the land of the gods. Bhu refers to the body. It is made up of Pancha Bhuthas (five great, elements). These five elements constitute Prakrithi (Nature). There is an intimate relationship between the body and Nature. The same five elements that are in the nature are also in the body.. Bhuvah is the Praana Shakthi (Life Force) that animates the body. Even if the Life Force exists, without Jnaana (Awareness) the body will be of no use. It is on this account that the Vedhas declared: "Prajnaanam Brahma" (Constant Integrated Awareness is Brahman). It is by the presence of Prajnaana that the Life Force is able to animate the body. The body represents inert matter. The Life Force operates in the body as a vibration. This Vibration derives its power from Prajnaana, which finds expression in radiation.Therefore, the body, the Life Force and the Prajnaana are all within man. The entire cosmos is present in miniature within man. It is because of these three constituents that we are able to see the cosmos and experience many other things. Every potency is within us. The external is a reflection of the inner being. It follows from this that true maanavathvam (humanness) is Dhaivathvam (Divinity) itself. Hence, the Vedhas declared that the divine appears in human form. Every human being is inherently Divine, but owing to his attachment to the body he' considers himself a mere man. How did this human body get animated by the Life Force? Whence has this Life Force come? It is from the Aathma-Shakthi (the power of the Self). Making use of this power of the Sell the Life Force carries out all activities.
