According to Vedic Religion, five Devtas are worshiped daily; Ganesh ji; Durga ji, Shiv ji, Vishnu ji and SUN;
Among all the devtas, SUN is the only one who is visible to us every day; Sun provides us and all the living beings with Light and life without any prejudice or discrimination. It rises every day to give us HIS blessings. Light means knowledge as Darkness means Ignorance. I very strongly believe that we must worship HIM daily. The best way to worship HIM is by chanting the Gayatri Mantra:
ॐ भूर्भुवः॒ स्वः ।तत्स॑वितुर्वरे॑(तत्सवितुर्वरेण्यं) ।भ॒र्गो॑ दे॒वस्य॑ धीमहि ।धियो॒ यो नः॑ प्रचो॒दया॑त् ॥
Proper chanting of Gayatri Mantra improves our intelligence and wisdom – a path for spirituality.
Its meaning and details are provided in several documents and websites; I would suggest:
