Tuning in to the greater reality of one who needs help will allow a level of understanding, and, ultimately validating their need, or not as the case may be, for your help – your service.
If when “tuning in” one feels that it is not necessary for YOU to be their liberator, and this is not a “way out of being of service”, then one can move on, because there is no karmic link between you both. However, ensure that the “tuning in” takes into account the possibility of creating karma – even if no karmic link was initially apparent.
Just because there is no link between two incarnates it does not mean that one cannot be created through neglecting the opportunity to be of service.
Those who request help, but do not need it, run the risk of creating their own karma – hence the need to tune in first. In this instance, gracefully declining help is helping to ensure that they do not accrue karma – linked to you, through false requests – which, is being of greater service in this instance.
