'gentle touch' is the definition.
'kiss' can be an answer for 'touch' (kiss is a kind of touch). I am unsure of the 'gentle' bit.

'some gracious sikh in retirement' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'in retirement' is a reversal indicator (retire can mean to go back or backwards).
'ssik' can be found hidden inside 'gracious sikh'.
'ssik' reversed gives 'KISS'.

'of' is the link.

Can you help me to learn more?
