Dharma is natural law. Dharma is nature. Dharma is the eternal way. Dharma is the eternal truth. Dharma is principles. Dharma is duty. Dharma is righteousness.  

A Dharma Rashtra (nation) is definitely supported in the Vedic scriptures. There are over 1 billion Sanatanis in India, and India is 79% Sanatani. The history and culture of Bharat is Sanatani. 

Modern Secular Hindus do not support a Dharma Rashtra (nation). Traditional staunch Sanatanis do support a Dharma Rashtra. 

Here are the verses that prove a Dharma Rashtra is supported in the scriptures, and all real Sanatanis should accept it and support Dharma nationalism:              

“Dharma sustains society. Dharma maintains the social order. Dharma ensures the well-being and progress of humanity. Dharma is surely that which fulfills these objectives.” (Mahabharata, Karna Parva, 69.58) 

“The proper function of the head of state is to govern according to Dharma and not merely to enjoy the luxuries of life.” (Mahabharata, Shantiparva, 90.3)

“He created still further the most excellent Dharma. Dharma is the ruling power of all ruling powers, therefore there is nothing higher than Dharma. Thenceforth, even a less powerful man rules a stronger with the help of Dharma, as with the help of a king.” (Brihadaranyaka Upanishad, 1.4.14)

 “Therefore, get up! Prepare to fight and earn glory! Conquer our enemies and take delight in a flourishing Dharma Imperium. The enemies of Dharma are already vanquished by My arrangement. You, O Arjuna, can be but an instrument in the fight.” (Bhagavad Gita, 11.33)

If you are a true traditional Sanatani then you will support a Dharma Rashtra (nation). 

 Dharma Rashtra victorious! 
 Victory to Dharma!
