This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
The exact historical development of 侼 is uncertain. It combines 亻 (person) with 孛, but the original meaning and component function are unclear.
A person 亻 beside 孛, a shape that looks like a child 子 under a cover 冖 with a cross 十 on top. Without a clear meaning, picture a person sheltering a child in a confusing situation.
For ホツ, imagine a person 亻 holding a hot ホツ cup of tea while sheltering the child 子 under the cover 冖. The hot cup cues ホツ.
