The twentyfour principles of the Sankhya school of philosophy are mentioned here.Great elements Earth? water? fire? air and ether are so called because they pervade all modifications of matter. The elements here referred to are the subtle? not the gross ones.Egoism is the cause of the great elements. It is the selfarrogating principle. Intellect is the cause of egoism. The function of the intellect is determination. Buddhi is the faculty of determination. The cause of the intellect is the Unmanifested (which is the undifferentiated energy of the Lord). (Cf.VII.14 Daivi hyesha gunamayi mama maya duratyaya -- This divine illusion of Mine? caused by the alities? is difficult to cross over.) The above Nature is divided eightfold (Cf.VII.4).The ten senses are the five organs of knowledge (ears? skin? eyes? tongue and nose)? so called because they enable the mind to get knowledge of the external world? and the five organs of action (hands? feet? mouth? anus and the generative organ)? so called because they perform actions.The one This is the mind. This is the eleventh sense whose function is thinking and doubting (Sankalpa and Vikalpa).The five objects of the senses are sound? touch? form (colour)? taste and smell. These are the fivefol pastures of the senses.All the great elements? egoism? intellect? the senses and mind are all absorbed in the Unmanifested at the time of the cosmic dissolution.Mind is Maya. Mind is Avidya (ignorance). Mind is at the root of all activities. It gives strength to desires? fosters fear and builds castles in the air. It confers force on egoism and stimultates,aspirations. Every tendency has its origin in the mind. It augments passions? gives strength to hope and awakens the sense of duality. It increases ignorance and plunges the senses in the ocean of senseobjects. It creates distinctions and differences. It separates? divides and limits. It is a strong wall or an iron barrier that stands between the individual soul and the Absolute. It is this mind that has brought Brahman to the condition of the individual soul. It is the storehouse of error? cravings? doubt? delusion and ignorance. It is an everrevolving wheel that generates thoughts. It is a miraculous thoughtproducing machine. It creates at one moment. It destroys at the next moment.

From all the authoritative statements of the great sages, the Vedic hymns and the aphorisms of the Vedānta-sūtra, the components of this world can be understood as follows. First there are earth, water, fire, air and ether. These are the five great elements ( mahā-bhūta ). Then there are false ego, intelligence and the unmanifested stage of the three modes of nature. Then there are five senses for acquiring knowledge: the eyes, ears, nose, tongue and skin. Then five working senses: voice, legs, hands, anus and genitals. Then, above the senses, there is the mind, which is within and which can be called the sense within. Therefore, including the mind, there are eleven senses altogether. Then there are the five objects of the senses: smell, taste, form, touch and sound. Now the aggregate of these twenty-four elements is called the field of activity. If one makes an analytical study of these twenty-four subjects, then he can very well understand the field of activity. Then there are desire, hatred, happiness and distress, which are interactions, representations of the five great elements in the gross body. The living symptoms, represented by consciousness, and convictions are the manifestation of the subtle body – mind, ego and intelligence. These subtle elements are included within the field of activities. The five great elements are a gross representation of the false ego, which in turn represents the primal stage of false ego technically called the materialistic conception, or tāmasa-buddhi, intelligence in ignorance. This, further, represents the unmanifested stage of the three modes of material nature. The unmanifested modes of material nature are called pradhāna. One who desires to know the twenty-four elements in detail along with their interactions should study the philosophy in more detail. In Bhagavad-gītā , a summary only is given. The body is the representation of all these factors, and there are changes of the body, which are six in number: the body is born, it grows, it stays, it produces by-products, then it begins to decay, and at the last stage it vanishes. Therefore the field is a nonpermanent material thing. However, the kṣetra-jña, the knower of the field, its proprietor, is different.
