This story contain deeper meanings for our contemplation.
First Wife
Our human body also has the elements such as blood, channels and drops for the practice of Highest Yoga Tantra - the quick path to enlightenment. Hence, we should maintain well our body so that we can utilise it to practise Dharma. Other than using our body for Dharma practice, the First Wife teaches us not to be attached to our body because we have to abandon it upon death. This body will also age and fall sick. These are suffering as stated by the First Noble Truth.
Second Wife
All that we have worked hard to accumulate in this life such as our wealth is of no use to us upon death. Like the first wife, we have to leave them behind. Hence we should not be attached to them. We can use them wisely to support our Dharma practice.
The second wife is also about the First Noble Truth which states that there is suffering, the suffering of having to part with what we like.
Third Wife
The Third Wife teaches about attachment. Since our presence in this life is short-lived, whatever relationships that we have developed become meaningless. There is a total separation from our loved ones when we die. We will also forget these relationships in our next rebirth. Hence we must be ready to let go of these relationships upon death. The only relationship worth developing is our relationship with our spiritual guide or guru who will continue to lead us on the path to liberation and enlightenment in the future lives.
Fourth Wife
Only our mind travel with us into the future lives. All our actions of this life and past lives are stored as imprints in our mind. When the conditions are right, these imprints will ripen into effects. Hence, we should be careful with our actions in this life which are dictated by our delusions of ignorance, anger and attachment. While we still can, we should purify as much as possible all our accumulated negative karmas in this very life so that these karmas do not manifest in the future to hinder our journey to liberation and enlightenment. We should also transform our mind by eliminating all our delusions as much as possible because delusions and their imprints are the obstructions to liberation and obstruction to omniscience respectively.
Yes, Sophie, we must be mindful at all times that we are not controlled by our anger. Anger is very destructive! It can extinguish eons of merits which we have accumulated but not dedicated for enlightenment. Apply patience which is the antidote to anger. Also practise accepting defeat and offering victory to others.
