  Nasadiya Sukta (Hymn of non-Eternity):
  
  Who really knows? Who can here proclaim it? Whence, whence this creation sprang? Gods came later, after the creation of this universe.
  
  Who then knows whence it has arisen? Whether God's will created it, or whether He was mute; Only He who is its overseer in highest heaven knows, He only knows, or perhaps He does not know.
  
  — Rig Veda 10.129.6–7
  
  The Rigveda Samhita is the oldest extant Indic text. It is a collection of 1,028 Vedic Sanskrit hymns and 10,600 verses in all, organized into ten books (Sanskrit: mandalas). The hymns are dedicated to Rigvedic deities.
  
  The books were composed by poets from different priestly groups over a period of several centuries between c. 1500 and 1200 BCE, (the early Vedic period) in the Punjab (Sapta Sindhu) region of the northwest Indian subcontinent. According to Michael Witzel, the initial codification of the Rigveda took place at the end of the Rigvedic period at c. 1200 BCE, in the early Kuru kingdom.
  
  The Rigveda is structured based on clear principles. The Veda begins with a small book addressed to Agni, Indra, Soma and other gods, all arranged according to decreasing total number of hymns in each deity collection; for each deity series, the hymns progress from longer to shorter ones, but the number of hymns per book increases. Finally, the meter too is systematically arranged from jagati and tristubh to anustubh and gayatri as the text progresses.
  
  The rituals became increasingly complex over time, and the king's association with them strengthened both the position of the Brahmans and the kings. The Rajasuya rituals, performed with the coronation of a king, "set in motion cyclical regenerations of the universe." In terms of substance, the nature of hymns shift from praise of deities in early books to Nasadiya Sukta with questions such as, "what is the origin of the universe?, do even gods know the answer?", the virtue of Dāna (charity) in society, and other metaphysical issues in its hymns.
  
  There are similarities between the mythology, rituals and linguistics in Rigveda and those found in ancient central Asia, Iranian and Hindukush (Afghanistan) regions.
