henkisiltä
Henkisiltä is a Finnish inflected form of the adjective henkinen, meaning "spiritual" or "mental." It functions as the elative plural form, used when the modified noun is plural and in the elative case. The elative case expresses origin or source and can also convey movement away from something. In practice, henkisiltä is used to describe sources, groups, or entities considered spiritual or non-material, and it typically appears before a plural noun in elative: for example, henkisiltä ihmisiltä saadut tiedot (information obtained from spiritual people) or henkisiltä lähteiltä peräisin oleva tieto (information originating from spiritual sources). The form is common in religious, philosophical, or cultural contexts, but its use is not limited to them.
Because it is a case form, it is not independently listed in dictionaries as a separate lexical
In usage, the nuance is that henkinen/henkisesti relates to non-physical qualities, beliefs, moods, or mental states
