Rigveda means the Veda of Adoration and mostly contains verses adoring or adulating deities. But it also dealt with other subjects, like the procedure of wedding, the folly of gambling. About two-thirds of Rigveda is about the gods Agni (Fire) and Indra (Ruler of the gods). Other Rigvedic gods include Rudra, the two Ashvins, Savitar and Surya, Varuna, the Maruts and the Ribhus. There are references to a divine creeper, the Soma, whose juice was an energizer. Some animals like horses, some rivers, and even some implements (like mortar and pestle) were deified. Rigveda contains a sense of intimate communion between Nature and the Rishis or visionaries. According to some, the concerns of Rigveda are those of simple, nomadic, pastoral Aryans. According to others, the people in the times of the Rigveda had a settled home, definite mode of life, developed social customs, political organizations, and even arts and amusements. Rigveda is the oldest, largest and most important of the Vedas, containing 10thousand verses forming 1017 poems in 20 groups.
