As the Vedas are vast and limitless, it was difficult and would take very long for ordinary men to study it. Hence, it was classified into four, so that it can be within the reach of all. The Rks or hymns in praise of the Lord were grouped under Rik Samhitha and Yajur Samhitha. The verses capable of musical rendition were grouped under Saama Samhitha and the formulae and spells were compiled under the Atharva Samhitha. There is no trace of conflict in any of these texts. They have emerged to enlighten people in different states of awareness to benefit from Divine Guidance and cross the sea of suffering.
