Death can be a very difficult time, both for the dying and the grieving. There can be feelings of helplessness, fear, uncertainty and great sadness and longing. The Tibetan tradition has a very simple practice to help both the dying and those who are acting as their support.
Begin the meditation by lighting a candle, some incense and recalling the person in your mind's eye. You may want to use a picture, but better is to simply feel their presence and the presence that they have had in your life.
With each exhale,
send out your love to them,
radiating out joy and happiness.
With each inhale,
take upon yourself their fear and sadness,
wholeheartedly relieving and supporting them.
uplifting their minds and hearts,
giving them confidence and clarity on the path ahead.
relieving their doubt and uncertainty,
their pain and sorrow.
At the conclusion of the practice, make additional prayers or recite mantras and dedicate your practice.
Generally this type of practice is done for seven to forty-nine days after death to ensure and support the transition to the next life, whatever that may be. It doesn't need to be elaborate, it can be as simple as sitting in a park, calling them to mind and sending them your love.
