When we say that everything has developed out of the Vedas, that means everything, literally everything.

Even administrative concepts.

Let us look at one of them.

In yajnas, the ladles are of four types- Sruva, Juhu Dhruva, and Upabhrit.

Normally, the rule is that if you take ghee in the Juhu, you offer ahuti in Agni with that only.

But there is an exception in the case of Upabhrit.

Ghee filled in Upabhrit is not offered in Agni from the Upabhrit itself.

It is done through Juhu.

Here, while taking the ghee also, ghee is filled into both Juhu and Upabhrit using another ladle called Sruva.

While filling also there is a rule.

Juhu is filled with four Sruva-fulls of ghee.

Upabhrit is filled with Sruva eight times, but a little-little every time.

स यच्चतुर्जुह्वां गृह्णन् भूय आज्यं गृह्णाति अथ यदष्टौ कृत्वा उपभृति गृह्णन् कनीय आज्यं गृह्णाति

Do you know why?

Juhu stands for the rulers of the nation.

Upabhrit stands for the wealth-makers of the nation.

Rulers are less in number, but more powerful.

They, even though less in number control the wealth-creators who are more in number but weak compared to the rulers.

तस्मादुत राजाऽपारां विशं प्रावसाय अप्येकवेश्मनैव जिनाति

Now the question comes up: why have a separate ladle called Upabhrit itself, an independent ladle if ahuti is not going to be offered from it?

Because wealth-creators need some amount of freedom and independence.

Then only they can create wealth.

Rulers are not supposed to create wealth.

They are there to control and regulate the wealth-creators.

Wealth-creators create wealth, but are they free to utilize it as they want?

No, they should not be allowed to.

Whatever is there in Upabhrit should go into Agni through Juhu only.

Juhu the ruler-class should control the utilization of wealth created by the wealth-creators.

The rulers should decide.

अथ यत्तज्जुह्वैव समानीय जुहोति तस्माद्यदोत क्षत्त्रियः कामयते अथाह वैश्यम् अपि यत्ते परो निहितम् तदाहरेति

These are Veda mantras, not Chanakya's Artha-shastra.

Whatever wealth you have created, bring it, we will decide how to utilize it; rulers tell the wealth-creators.

अथ यत्तज्जुह्वैव समानीय जुहोति तस्मादिमा विशः क्षत्रियाय बलिं हरन्ति

This is the concept of both taxation and regulation.

From the Vedas.

Give wealth-creators freedom so that they can create wealth.

But they should not be free to spend as they like.

That should be under the control of the government the rulers.

Both at the same time, freedom and regulation it is from such mantras that Smritis, the rule books develop.

Neeti-shastra and Artha-shastra develop.

This is why we say Vedas have everything in them.
