Here's a breakdown of the meaning:
* राज (rāj) means "king" or "royal"
* मुद्रा (mudrā) means "seal"
Therefore, "Rajmudra" refers to a seal used by a king or other royal authority to authenticate documents, decrees, or other official writings.
In Marathi, the term might also be used figuratively to denote something important, valuable, or powerful, just like the seal of a king held great significance.
