Where can I find correct source of Mantra Pushpanjali?

Question

I'm concerned about Mantrapushpanjali

The doubt is in this sentence:

ॐ राजाधिराजाय प्रसह्यसाहिने नमो वयं वैश्रवणाय कुर्महे | स मे कामान्कामकामाय मह्यम् कामेश्वरो वैश्रवणो ददातु | कुबेराय वैश्रवणाय महाराजाय नमः || 2 ||

In the end, you see महाराजाय नमः

Now, I tried to find same on many other sources and all of them had same words, especially the Namah.

But doubt arose when I heard this on Star Plus Mahabharat. It is clearly heard them singing like "महाराजाय विद्महे" instead of "महाराजाय नमः"

I also noticed them pronouncing दधातु instead of ददातु.

So I'm not sure which one is correct and which one to trust.

How do I determine which one is correct/pure or where can I find correct source of Mantra Pushpanjali?

Note: If you want to hear it yourself, just type "Mahabharat Rajyabhishek Mantra" on YouTube and hear in the end, you'll understand my doubt.

Answer 1

This shloka is from TAITTIRIYA ARANYAKA 1.31.6.

https://www.youtube.com/watch?v=NaSjtamHFNk here you can hear the shloka from 1.11.46

https://vedicheritage.gov.in/aranyakas/taittiriya-aranyaka/# meanwhile this is from vedic portal by govt of india , you can hear from 1.01.27

so clearly pronunciation is महाराजाय नमः only and not दधातु but ददातु.
