what is your problem? If you don't want to know what a tatpurusha is, simply ignore it. We cannot taylor articles according to what you think people are looking for. You have some cleanup ahead of you if you want to see this through, buddy. I suggest you begin by removing the superfluous Devanagari from all India-related articles. Feel free to come back here once you have cleansed Category:Hindu deities of such redundancy of no interest to high-schoolers.  (𒁳) 

 I can easily slap your own argument back at you by saying what is your problem if the tatpurusha mumbo-jumbo is included somewhere later in the article. Till now, you have not given one valid reason why such technical terms need to be planted right at the top in the introduction, when it is very clear that most average readers, quick-surfers etc. are just looking for a definition, and a brief intro. That is the primary reason all encyclopaedic articles have an introduction in the first place.

Devanagiri scripts are not "technical terms". They are a translation and people understand that. You know the crux of my logic DBachmann, but are skillfully skirting the issue by bringing in the similar but unconvincing argument of Devanagiri scripts into the discussion. The tactic of "if this, so why not this" does not apply here. Devanagiri can remain, but tatpurusha compound etc does not.
