These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ho Yay: Almost everyone loves Buddha, and some conversations about him can seem a lot like this out of context. Also, what with practically everyone running around shirtless, many waist-up-only panels between the predominantly male cast can look like something else.
Also, Tatta and Yatala, as mentioned above.
Tear Jerker: Many. Asaji's and Chapra's deaths come to mind. Buddha after Tatta dies. When Tatta was willing to be eaten by a snake so that his friends could live. Praesenajit dies without seeing Buddha again. This manga has so many that it has its own page.
It Makes Sense in Context. This happened in Antiquity, before the Maurya Empire (the first major Indian civilization). Given that every Iron Age civilization had some level of acceptable public nudity, not to mention that Gautama Buddha's Jain contemporary Mahairva was known to travel naked after enlightenment, there is some historical justification. Modesty didn't really develop in the subcontinent until the Middle Ages, possibly not even until after the Islamic conquests.
