Puranas and Itihas (of vedic tradition)

while many Vedic spiritual concepts are simple logics to understand,
still there are people who do not understand them on their own or at least after someone tells, due to their limited intelligence or due to hatred.

for such people..the beginners or common people, there are many puranas, books and poetry to teach basic things like.. the best relationships of a family, the best way of life, different personalities in life, etc (eg: Ramayan and Maha Bharat). Yoga teaches healthy living. Ayurveda is a good medicinal science. Astrology is for knowing the future. All these help common people in different ways.
