Answer this question to the best of your ability:
Are there any signs that indicate that one has mastered skillful compassion meditation?
Mastery in skillful compassion meditation is not about reaching an end-point, but rather about continuous growth and deepening of one's practice. However, some indicators of progress include increased self-awareness, better emotional regulation, improved empathy and compassion for others, and a greater sense of inner peace and wellbeing. Additionally, you might notice that challenging situations elicit more compassionate responses from you over time.
