Aadesh (Ādeś) is a traditional Nath salutation and a word connected with instruction, direction or command. In certain Nath interpretations it carries a deeper philosophical sense: a reminder of the underlying unity of the embodied being, the self and the supreme reality. Practitioners may use it to greet gurus or fellow yogis with respect.
That spiritual explanation is lineage-contextual rather than a universally agreed translation of the Sanskrit word. In ShivGoraksh, Aadesh is also the name of the AI knowledge guide; this is a respectful product name, not a claim that the software is a guru, initiate, divine voice or bearer of lineage authority.
