In plain words
Whether they are valuable or not, he has no hold over them at all. But when he goes back to his own place he packs everything in the house, thinking it is his, and takes it with him. What is joined with the sense of mine is māraka; what is free of the sense of mine is tāraka. "Not mine": that is true tāraka. "Mine" is māraka. In the same way man today grows a sense of mine over every small thing, piles even worthless things on his head, forgets time, action and duty, and struggles for them in many ways. When the mind is let spread out over the objects of the senses, it becomes bound. To set the mind on these negatives and struggle for them is nothing but māraka. However valuable the things he holds within him, the man held by the sense of mine gives them up and toils in this way.
This body is a worthless iron box, and into such a thing we put all the precious jewels. But what is kept inside is what matters. This body is like a temple. The indweller in it is like a foreign diamond. When you put jewels in a box, is the value in the jewels? In the box? The jewels are what is precious. In the same way man forgets the principle of the indweller, who is eternal truth in him and always leads him on the right path, and struggles after worldly, material, passing things. That is why man joins himself to so many bonds and falls into sorrows. What is the reason for this? The root causes are the fourfold antaḥkaraṇa: Manas, Buddhi, citta and Ahaṅkāra. The eyes long to see anything at all. They do not ask what kind of things they should see. Our aim should not be merely to look about because we have eyes. To see is the nature of the eyes, but what kind of thing should they see? The ears take great delight in hearing. They do not put the question, what kind of thing should they hear. To eat is the nature of the mouth, but people do not ask what they should eat. To smell is the nature of the nose. But what kind of thing should one smell? To touch is the nature of the hand, but people do not ask what they must not touch.
