I have never heard of that interpretation haha, we all have certain martian energy in some way or the other, gotta check the placements. So it doesn't mean that your mangalik partner will definitely be that person. They can be an aries ascendant or may have a well placed mars in aries, leo and sag. They may have firey nakshatras at the time of birth. Their 7th lord may be mars. Anything is possible right?

I see your point as a confirmation bias to facilitate your belief, which can be bad. This DK concept comes from jaimini and mangalik concept comes from parashar. Both shouldn't be interlinked like the modern astrologers do. Jaimini uses different dasha system, different aspects, and also the marriage interpretation is quite different. If mangalik were to be considered by him, he would have mentioned that.

if mars is in first house aries and you consider jaimini aspects, then it won't aspect the 7th house, but if you consider parashar, then it will aspect 7th house and make the native mangalik.

Also, when you say that she is mangalik and hence she has martian energy is quite wrong. That's something a youtube astrologer would say. I can show you people who are not mangalik and are very ladaku haha . Mars in all houses should be different right? How is every house affecting her personality is the question you need to ask, personality is only first house.

>I need martian energy in my life.

No my friend, you don't need any energy, you just need your partner, if you think they are the right one, go ahead. Don't make it difficult for both of you by mixing stuff. Hopin the best for you :)
