not performed correctly has no efficacy. Religion, therefore, is in the hands of this caste, whose sacredness is hereditary, and cannot be acquired in any other way than by birth. The members of that caste and they alone are qualified to superintend religious observances, and without them the intercourse between man and the gods cannot be kept up. From his birth the brahman is a being of superior holiness; he is destined for higher ends than other men, and the distinction between him and them must be manifested in all his acts and habits throughout his life. He is the natural lord of all the classes. [Footnote 1: Compare Hans Sachs, _Die Ungleichen Kinder Eva's_.] If the highest caste is strictly defined, so also are the others. The second caste is that of the Kshatriyas, warriors or rulers, the third that of the Vaisyas or farmers. These three have rank, they are the twice-born classes (their second birth answers to confirmation, and takes place when a young man is invested with the sacred thread). The Sudras are the fourth and lowest class; no duty is assigned to them in the law books but that of serving meekly the other castes. It has been thought that the Sudras represent the conquered aborigines, the three classes of rank belonging to the Aryan invaders, but this is open to question. The student of religion has to fix his attention on the Brahmans, who have secured themselves in the position of the leading caste. We speak first of the literary movement in which they were concerned, then of the sacrifices they conducted, and of their gods. We shall then say something of the practical operation of their religion as a rule of life, and lastly we shall come to the speculative work of their period, which is not, however, to be set down to them alone.
