At times we may feel regret in loving others....it is caused by our own expectations. When we find others who we feel are unworthy of our love...we must also look at ourselves and consider that we have been unworthy of love in the past and not always as appreciative as we could have been for the wonderful people and conditions that came into our lives. We often blame others for our own karma.
It is often only when these conditions and people are gone that we recognize just how much love God has given us.
Sometimes we feel faced with the unworthiness of loving others who are unable or unwilling to love us only because we ourselves have not always been receptive to the love offered us. But as time goes on we find that we do get love from others...but not always in the way we thought it should be given to us.
Wisdom free from time.
Namaste.
