Verily, the Rig Veda is the source of all Vedic Knowledge. When Sage Vedavyasa compiled and categorized the Vedas, the first Veda he took up was Rig Veda. Rig Veda is derived from the Same word ‘Rik’ which means, ‘to invoke’, to praise (the divinity)’ ‘Rik’ has been derived from the root ‘Ruchastutau’. In Rig Veda, all the Mantras are in praise of and glorifying all the Gods, such as god of fire, god of rain, Lord Vishnu, etc. Hence it got the name, Rig Veda. According to ancient lore, the Rig Veda originated from a place called Lohapuram (current day Lahore in Pakistan) on the barks of Sindhu River. This Veda is mainly used in Yagnas to invoke and all the gods Big Veda is composed of many Ruks’ It is a Veda that deals anh Gods, just as Yajur Veda deals with human beings, and Sama Veda deals with ancestors.

Sage Saunaka described the Rig Veda as having 10,500 Ruks. Each of the Ruks in Rig Veda is in the form of ‘Padya’, i.e., it is imbued with Chandas. Each chandas has clear rules about the number of alphabets (aksharas). There are five Shakhas in Rig Veda, Shakala, Bhaskala, Aashwataryana Maandukya and Sankhyaayana. At present, the only surviving Shakha in Rig Veda shakala.

In Rig Veda, there are three parts, namely Samhitas, Brahmanam and aranyaka. In the aranyaka portion, there are live Upanishads that include Aitareya Upnishad and Samhitopanishad.

Samhitas in Rig Veda in contemporary portance is viewed in two different forms. These are respectively Ashtakaas and Mandalaas. Ashtakaas are divided into Adhyaayas (lessons, which are further divided into Vargas Mandalaas are divided into Anuvaakas and Suktaas. In South India, the most common form of viewing Rig Veda, is Ashtakas. In this form of viewing, in the Samhinita portion of the Rig Veda, there are eight Ashtakas, each having eight Adhyayas. Alternately, the same Rig Veds is viewed as having ten Mandalaas, in North India,Rig Veda is viewed as having ten Mandalas.

In the expansive landscape (1017 suktaas having 10500 Ruks theme are 1,53,825 shabdas (words). These are comprised of 4,32,000 hrs (fundamental characters in Sanskrit), as per the description of Sage saunaka. Very coincidentally, it is said that  the current epoch(kali  Yuga) will last for 4,32,000 years. 

Rig Veda has six branches of learning. Astrology (Jyotish Shastram) is one of these branches.It is embedded in one of the Suktas of Rig Veda (in  the 2nd Ashtakaa,3rd Adhyayam,from  the beginning of Asyavaamasya Suktam and continues thereafter for 52 Ruks ).
