Chanting this mantra for the dying

Naran S Balakumar “OM HOWM VUM JOOM SAHA” How will you determine whether the person is dying or not? If the doctors put the patient in ventilator, then you can start chanting this mantra, even while sitting at home. Because ventilator means the life is weaker.  In general, aged people won’t come alive out of it. Even if they come out, they won’t be alive for long.
