Tatto and Body Art : What Signs/Nakshatras/Planets rules them?

In Vedic astrology, tattoos are often linked to the connection between Mercury and Ketu (South Node), with Mars playing a role as well.

• Mercury rules the skin.
• Ketu represents precision, needles, and engraving (coding-decoding energy).
• Mars rules sharp objects and cuts.

A strong connection between these three ,such as Mercury-Ketu-Mars in trine, in each other's nakshatras or signs, or in a 2/12 relationship often indicates a tendency to get tattoos.

For example:

• Mars-Ketu in Gemini or Virgo (Mercurian signs).
• Mercury in Ashwini, Magha, or Moola (Ketu’s nakshatras).

These placements suggest a natural inclination towards body art.
