156 DR. BABASAHEB AMBEDKAR : WRITINGS AND SPEECHES
touch others or marry with them; and besides these eighteen castes of the Heathen who are natives of Malabar, which I have now related to you, there are others of outlandish folk, merchants and traders in the land, where they possess houses and estates, living like the natives, yet with customs of their own.”
These foreigners were not able to give a full and detailed picture of caste. This is understandable. For to every foreigner the private life of the Hindu is veiled and it is not possible for him to penetrate it. The social organism of India, the play of its motive forces, is moreover, regulated infinitely more by custom, varying according to locality and baffling in its complexity, than by any legal formula which can be picked out of a legal text book. But there is no doubt that caste did appear to the foreigners as the most singular and therefore the most distinguishing feature of Hindu Society. Otherwise they would not have noted its existence in the record they made of what they observed when they came to India.
Caste therefore is something special in the Hindu Social organization and marks off the Hindus from other peoples. Caste has been a growing institution. It has never been the same at all time. The shape and form of caste as it existed when Magasthenes wrote his account was very different from what the shape and form it has taken when Alberuni came and the appearance it gave to the Portuguese was different from what it was in the time of Alberuni. But to understand caste one must have more exact idea of its nature than these foreigners are able to give.
To follow the discussion of the subject of caste it is necessary to familiarize the readers with some basic conceptions which underlie the Hindu Social organization. The basic conception of social organization which prevails among the Hindus starts with the rise of our classes or varnas into which Hindu society is believed to have become divided. These four classes were named: (1) Brahmins, the priestly and the educated class, (2) The Kshatriyas, the Military Class, (3) The Vaishyas, the trading class and, (4) The Shudras, the servant class. For a time these were merely classes. After a time what were only Classes (Varnas) became Castes (Jatis) and the four castes became four thousand. In this way the modern Caste System was only the evolution of the ancient Varna System.
No doubt the caste system is an evolution of the Varna System. But one can get no idea of the caste system by a study of the Varna System. Caste must be studied apart from Varna.
