An individual who has a firm determination to be reborn a human and meet Buddhism is the one that this life may be miniscule, but this life only brings about real happiness since it is the most meritorious in all aspect.
Whatever one does, one can do only in this life, and receive the best outcome, that is, the Nirvana which leads to the Cessation of Suffering. One can do good to ascend into heavenly realm only through this life.
To have a resolution not to be reborn in other state of existence after departing this world is the highest blessing in life.
