In plain words
All of these concern the body! ‘I am a Brāhmin, I am young, I am old, I am a man, I am a woman’: all these effects concern the body alone. This is not knowing oneself. To know the one who dwells in the body is to know oneself. It is not knowing this body: you must know the one who owns the body. Merely knowing the kṣetra is not knowing oneself; you must know the kṣetrajña. ‘Know Me also as the kṣetrajña’, it was said. The oneness of these two is humanness, it was said. To know this kṣetrajña, the kṣetra called the body is needed. Only when we set this kṣetra on the proper path does the sacredness of the kṣetrajña become clear to us. In what way are we to spread and teach all these divine powers that are in man? What are the chief qualities we must have? A mind like butter, a heart like moonlight, speech like honey: when we develop these three, that is the right path to Divinity. Look at the mind: it is very bitter. Look at the heart: it is very fickle. Look at the words: they are very harsh. This is no sign of humanness. It is only a sign of cruelty. Every man's word must be a word like honey. The heart must be a heart like moonlight. The mind must be a mind like butter. That is the Divinity in humanness. The spiritual path helps a great deal in finding such existence of God. By any path at all we can reach God. That is why it taught the nine kinds of path, proved the truth that the goal is one, and has kept teaching that divine remembrance of the Name is the true royal road to it.
Picture in your heart the feeling that all karma is to please God
Whether you do dhyāna, do japa, do tapas or perform the sacrificial rites, the Name is their root and ground. The whole Ṛgveda is made up of the Name. The whole Yajurveda is joined with mantra. The whole Sāmaveda is made up of song. Song, the Name and mantra: man's heart is made up of these three.
