Is anyone here going to explain what's the difference between Buddha and Parvati? Because I have no idea who Parvati is.
I'm going to be honest, I find it very hard to understand why you're even comparing the two. Let me preface by saying that Hinduism and Buddhism have dozens upon dozens of sects so what I am saying is very general and could be considered true in one place and false in another, that being said.
Parvati is a human turned diety in Hinduism married to one of the big three gods, Shiva (the other two are Brahma and Vishnu for reference). She's the Goddess of Love and her most famous mythological story in the West is probably how she married Shiva. She's the second wife because Shiva's first wife (Sati) throw herself in a funeral pyre for reasons. This sent Shiva into a funk and he fucked off to the Mountains to do yoga and shit. Sita got reincarnated into Parvati as a human. A demon named Tarakasura shows up and tricks the creator diety, Brahma, into making a whole bunch of restrictions on who can kill him. Basically, no Gods or Humans can kill him, only a son of Shiva and a human girl will do. Gods really need Parvati and Shiva to bang, but Shiva is going full monk mode and wants none of that. So they send Kama (can be very loosely interpreted as Hindu Cupid) to shoot Shiva with an arrow to get him to bang Parvati. Kama tries to fire the arrow and Shiva incernates him for this, asks why the gods were trying to get him to bang Parvati, and says basically 'wtf why you didn't you just ask, if saving the world only requires me to fuck this broad I'll just do it bro", and then they have a child who kills Tarakasura which is a story for a different time.
The Buddha mentioned here is most likely the original Buddha, a man named Siddartha Gautama from Anicent India (I'm honestly confused why anyone is claiming he is Nepalese. In a modern context sure, but at the time, Nepal was not independent. It's like saying "Ares should be considered a Spartan diety, not Greek") He is the founder of an entire religion and to try and cover all of what he is considered would be as relatively difficult as establishing who Jesus was in a paragraph. The very short and simple most common version was that he was a prince sheltered from the outside world and all it's negatives, suffering, illness, death etc. until one day when he was a teenager he snuck out. Suddenly, the Buddha was made aware that living fucking sucks, and has a breakdown about it. He disavows all of his wealth and worldly pleasures and fucks off innawoods to become an ascetic, a highly religious individual that avoids all pleasurable things in pursuit of religious knowledge. He finds out that starving yourself, working yourself to the bone, and sleeping uncovered outside naked it pretty fucking miserable too, so he gives up on that. Finally he says, I will sit underneath this tree until I figure out how to end all suffering, and eventually, he did. He proposed that instead of mindlessly indulging in carnal pleasures, and instead of mindlessly pursuing ascetic torture, a middle path could be chosen that would allow people to escape all suffering by the clearing of the mind and body through various practices.
This is again, a heavy, heavy generalization, but if you want more in depth discussion, I recommend reading up on it yourself. I would like to reiterate I have no clue why you're even associating the two, as far as my admittedly limited knowledge goes their only connection is that Parvati is related to Hinduism, and Hinduism is related to Buddhism.
