In 1830 he organized the society known as the Brahma Samaj.
Thus the pious Hindu, confronted by the impossibility of obtaining perfect knowledge by the senses or by reason, finds his sole perfection in the contemplation of the infinite (Brahma).
It is this intrinsic power of fervent invocation and worship which found an early expression in the term brahma; and its independent existence as an active moral principle in shaping the destinies of man became recognized in the Vedic pantheon in the conception of a god Brihaspati or Brahmanaspati, " lord of prayer or devotion," the divine priest and the guardian of the pious worshipper.
By a natural extension of the original meaning, the term brahma, in the sense of sacred utterance, was subsequently likewise applied to the whole body of sacred writ, the tri-vidya or "triple lo re" of the Veda; whilst it also came to be commonly used as the abstract designation of the priestly function and the Brahmanical order generally, in the same way as the term kshatra, " sway, rule," came to denote the aggregate of functions and individuals of the Kshatriyas or Rajanyas, the nobility or military class.
In the later Vedic writings, especially the Brahmanas, however, Prajapati still maintains throughout his position as the paramount personal deity; and Brahma, in his divine capacity, is rather identified with Brihaspati, the priest of the gods.
