The major concern is to be sure the person is at a stage where leaving is possible, that it can be arranged and supported by the divine realm once the person is more in an alignment with that choice on the level of the deep subconscious in particular. If you are encouraging someone to leave the body who is in a temporary state of emotional anguish, or frank mental imbalance who is suicidal, this may indeed truncate much prior planning for the lifetime to perhaps even take on this life-threatening circumstance and surmount it, not by exiting and leaving the body behind to die, but to seek healing and overcome the impairment and return to a better life, and eventually flourish for some time yet before the true eventual age where passing is inevitable. This can be ascertained through consultation with the higher self or with Creator for each individual circumstance to determine whether this is in divine alignment and is truly highest and best for the individual.
In most cases, this will be brought to your attention by a third party, a family member most typically, with a vested interest that may be a loving humanitarian concern for their best welfare, or a mixed agenda, or even a very cynical desire to see the person expire because they will inherit something or reduce their expense and gain materially from the person’s demise. It matters not the motive of the sponsor, the only thing that matters is the wellbeing of the person receiving the assistance, whether it is appropriate and in divine alignment, and highest and best for their soul progression. So once that is ascertained, support can be given and this can be done regardless of what others think, even loved ones.
So there may well be a very complex mixture of motives and desires in the case of a particular individual with one or more family members cheering on an assistance with transition but one or more others in the family desperately clinging to the impaired individual, and sees their death as an unthinkable, unimaginable, and intolerable loss for them personally, and may well believe the person who is languishing is still benefitting in some way, and this constitutes actual murder.
People are unpredictable and are often irrational in some aspects of their thinking, so this will be a very complex arena in many respects and will require great care and understanding to deal with those who have a stake in things. You cannot be blamed for things beyond your awareness but once there are objections and concerns brought to the fore, there will be fallout and a potential backlash if you go against someone’s wishes even though you might have a majority assent to proceed. These will be human‑level emotions and consequences and, therefore, you must bring human-level judgment to bear on the best way to handle things.
We can instruct you that what matters is the person suffering, and if this causes harm or emotional distress to a relative, it is a lesser evil than to keep a person trapped in a state of torment simply because someone else is dependent on their existence for their sense of personal security. But you must also reckon with human actions, including legal action, and what can be done potentially to cause trouble for you. We can be of assistance in sorting out the players and the likely scenarios that might arise in a given circumstance.
In most cases, such complications will not be likely because the people, for whom you are envisioning employing this strategy, are simply barely hanging on to life with no visible benefit to anyone, other than they still are breathing and are not technically dead. As you know, many people will continue life support for loved ones indefinitely even though they are in a vegetative state, but it is unlikely such individuals for whom the family has a strong possessive involvement in wanting to preserve their life at all costs, even only in a mechanical sense, will not be seeking you out for services of this kind. So, as in many situations where people turn a blind eye to the spiritual and suffer as a consequence, such will be the case here—there will be many who are denied this blessing because of the prejudice of care givers and the ignorance in being unaware of the possibilities and the true value of a spiritual solution for the suffering of their loved ones.
