In plain words
The seer is the Ātma. The seen is the world, an imagined creation. Man, endowed with intellect, must try to separate the joined form of these two. That is vibhāga yoga. Whether we call it the yoga of the division of the three guṇas, or the yoga of the division of the kṣetra and the kṣetrajña, it is the same. In the body, called the kṣetra, dwells the Ātma, called the kṣetrajña. But because man makes the seer and the seen one, that becomes the cause of sorrow. That is precisely why we must separate the seer and the seen. We must keep the seer alone as our goal. All that is seen is bound to change.
Every human being must keep two things well in mind. One is giving; the second is dying. But nobody agrees either to give or to die. What, after all, is the goal of life? Life is not for enjoying pleasures and joys as long as we live, only to die like dogs and jackals. We must live an ideal life. Humanness is not a separate path; it is a way of living. Character must change; there is no use in changing clothes. The mind does not change through books. We must shape this in the many tasks we do in daily life, in daily experience.
The Body and the Nation
The body itself is the nation: the body is the subtle form of the nation, which is the gross form; whatever five elements, five sheaths, five tanmātras and five prāṇas there are in the nation, all of them are in the body too. If we recognise the principle of the body well, the principle of the nation is easily understood. To understand the principle of the body, we must watch the principle of the mind carefully. We must see whether the mind runs in keeping with humanness or against it.
Today people cast off their own ideas and take others' philosophies and thoughts as their ideal. To win the freedom of Bhārata, they took up the boycott of foreign goods and the use of home-made goods as a means. To win self-rule too, the empire of the Ātma, we must follow certain rules.
