The decision to help all beings achieve enlightenment and happiness is the meaning of being a Bodhisattva. This can take many forms, and may happen in life, or happen after choosing to descend from heaven to help others.
Senses, something alien after a thousand years, scents of a forest, the feeling of the hard ground around you, it’s overwhelming. The sun is bright, even behind closed eyes. You pull on the ground and hoist yourself to a sitting position finally opening your eyes. … White… a white path seemingly going on for miles, with the faint outline of a building in the distance shadowed by the morning sun. It seems familiar, where are you? A snap, you clutch your head in pain, memories coming to bear all at once in your brain, you see them, fighting for your attention, a war, a journey, a decision, too vague to make out amidst the pain, but one thing stands out as the memories fade, the reason you descended.
You remember now, your sister, Byakuren. So distraught by death she sought immortality. The very antithesis of your teachings, even worse, she has resorted to working with Youkai. Because of this, you have received a mandate, either move her from this path, or kill her.
But first you must find her, a quick glance shows the path is made out of ornate stone, marked by lanterns of the same material, it’s well worn and appears to be traveled frequently, behind the path goes on around a corner, but you can see smoke in the distance, a village perhaps?
Around you sits a forest, thick, and undisturbed.
Where are you going?
 Make your way towards the building.  Head towards the smoke.  Veer off into the forest.
First time posting on THP, not a new writer but I have never written a story publicly before, majority of what I have written are role-playing campaigns and settings, so criticism is nessecary at this point, thank you.
With a heavy sigh you start the slow walk towards the building in the distance, gazing at the landscape as you do so, the forest is untouched, very few signs of human interference, besides the path of course. The path itself is carved white stone of high quality, dirtied only slightly by travelers and animals.
At least an hour has passed since you have started walking, as the sun has moved from its midday position, but the building comes no closer, nor does the smoke grow farther away, it’s impossible to tell if you’ve made any progress, besides the lanterns there are no landmarks.
A few hours pass with little progress. Though you have realized the sounds of the forest have tapered off to nonexistent, yet the building is ever far away.
As you turn to check behind, the path is gone, no more than ten feet behind you it ends abruptly in a closed circle, marking the end of the path, what used to be the road is now a clearing surrounded by a bamboo thicket.
In this clearing lies a manor, old and in disrepair, with no ready signs of life.
The sun is setting, casting an orange glow over the environment.
What do you do?  Continue on the path as before.  Investigate the structure.  Make camp at the tree line.  Veer off into the Forest.

I'm sorry if this comes off as antagonistic, but you might want to brush up on your Buddhism more. Familicide isn't... isn't usually on the table as an option. I mean, even the BUddha rehabilitated Parvati's cannibalism instead of sealing her away, while Sun Wukong basically got parole and eventually became a Bodhisattva himself.
Either Myouren's been possessed by something, this isn't really Myouren, or Myouren's a terrible BUddhist like his sister.
Buddhism isn't actually magic-intolerant. See Sun Wukong again, who used and abused Taoist spells for giggles and profit. Byakuren's magic is specifically mentioned as evil, but she only learned that specific brand after Myouren kicked the bucket.
What >>36740 said. The Buddha didn't seal Sun Wukong because he was using Taoist magic, he sealed Sun Wukong because he was a dick. Had Monkey just did other things like not piss off the entirety of Heaven then the Buddha wouldn't have done anything.
Byakuren's a terrible Buddhist, not because she tried to be immortal or because she looks out for Youkai, but because she looks out for Youkai above humanity. The goal of Buddhism is to stay detached and be able to help others without investing your sense of self into 'helping', and Byakuren as she's usually portrayed is too emotional for that.
Being a terrible Buddhist doesn't mean you're a terrible person. It just means you don't follow the tenets of Buddhism very well.
Lastly, if the implication that Myouren is a Bodhisattva is true, then there shouldn't really be any 'mandates' involved. The First Buddha doesn't really get head hancho ordering abilites over Bodhisattva, each one just does its own thing. Going back to Sun Wukong, the Emperor of Heaven didn't mandate Sun Wukong to be sealed, he just asked if the Buddha could do anything about it.
For a story that might be based entirely around Buddhism, it just feels... incredibly 'off'.
My own suggestion is to do some more research on Buddhism and then try again. Like any religion/philosophy, Buddhism has offshoots and disagreements, and you might be able to find something to play off of between Myouren and Byakuren. Seeing how the elder Hijiri deals with Gensokyo would be interestng, as well.
