What about those who have no love for flowers in general and no love for roses in particular ?
Those have a most serious spiritual damage and reject love. Such persons are unfit for relationship and should be allowed sufficient time - if necessary a full lifetime - to cure their own self before entering a love relationship.
Yes there are millions of people on this planet who forcefully reject any approach to love and who have consciously selected a path of darkness, aggression and rebellion. Only God can help such persons, during the course of time, curing the course of many reincarnations if necessary these people will receive a large number of different situations to heal their own self step by step and to become ready again to love. To give love and to receive love.
