'self-kindness' originates from the combination of 'self' and 'kindness', where 'self' refers to one's own person and 'kindness' means the quality of being friendly, generous, and considerate.

'self-kindness' is a modern term that combines the words 'self' and 'kindness' to emphasize the importance of treating oneself with the same compassion one would offer to others.

Initially, 'self-kindness' was not a common term, but it has evolved to emphasize the importance of self-care and mental well-being.
