What are the vedas in sanatana dharma?

Vedas proclaims the ultimate truth of the universe. I admit my Spiritual Master has explained to me the essence of all the FOUR vedas, and though describes very minutely could not explain the Origin of God/universe. (VEDANKALALUM KANDU ARIYA MUDIYADHAVAN KADAVUL., KADANTHU NIRPAVAN KADAVUL. BHANEWALA ITHI BHAWAN) .gOD IS THE ONE WHO WILL ALWAYS ON THE RUN IF YOU CHASE him. that is the meaning. But GOD gives His vision to those people who arrealise Him through true devotion, Self enquiry etc., but the faith should unquestionable. merely saying I love God, IPRAY him and J BELIEVE hIM WILL NOT DO. aGAIN VEDAS GIVES AN ORDER HOW YOU SHOULD LIVE. it says satyam vada, dharmam chara, matru devo bhava, pitru devo bhava, athithi devo bhava dhurbalam rasha etcetc. Meaning it commands you you should always speak thevtruth only, follow the rightious path, treat your mother, father and guests as GODS, help the weak and the poor. etc. etc.
