I edited my post with a disclaimer of sorts...
Also, going to a neighbouring country to visit family is common for an asylee to do. There's nothing to worry about there, especially if you don't actually go to Nepal (since there really is no immigration control between the two countries, it would be hard to prove you went there without a search of your belongings for signs of travel to Nepal). So, if your asylum case is such that a visit to Nepal won't really put you at risk, you can essentially go if you feel that it is safe (and, you can justify it during your naturalisation interview IN CASE you want to be honest about it, or they somehow find out). It's all relative.
Good luck, and please let us know how it goes.
