Originally the One Veda was divided into four by Srila Vyasadev. Then the follower's of Vyasadev sub-divided the Vedas into 1130 branches.
eka-vimsati-bhedena rg-veda krtavan pura
sakhana tu satenaiva yajur-vedam athakarot
sama-veda sahasrena sakhana prabibheda sah
atharvanam atho veda bibheda navakena tu
Formerly the Rg Veda was divided into 21 branches, the Yajur Veda into 100 branches, the Sama Veda into 1,000 branches, and the Atharva Veda into 9 branches. - Kurma purana 52. 19-20
Each of these branches has 4 subdivisions called Samhita, Brahmana, Aranyaka, and Upanisad. So all together the Vedas consist of 1,130 Samhitas, 1,130 Brahmanas, 1,130 Aranyakas, and 1,130 Upanisads, a total of 4,520 titles. By the influence of time, however, many texts have been lost. At present only about 11 Samhitas, 18 Brahmanas, 7 Aranyakas, and 220 Upanisads are available. This constitutes less than 6% of the original Vedas (source: Veda - Vedic Knowledge online)
Therefore it is in our own self interest to seek out the essence of the Vedas. After all the idea behind studying the Vedas is to find the truth. The truth has been succinctly explained by Lord Krishna in the Bhagavad Gita. He says;
vedaiś ca sarvair aham eva vedyo
vedānta-kṛd veda-vid eva cāham
By all the Vedas, I am to be known. Indeed, I am the compiler of Vedānta, and I am the knower of the Vedas- BG 15.15
Anyone serious to understand the conclusions of the Vedas should not waste time searching for it but simply accept the words of Krishna as truth. Indeed there is no other scripture or being in this world that declares such a bold statement - krsnas tu bhagavan svayam, Lord Sri Krishna is the original Personality of Godhead.
