The experience of transcendence occurs within the nature of things -- our nature. A small mustard-seed grows into a tree big enough for birds to come and roost in its branches. To try to make it grow faster or slower would be absurd and counterproductive. It is the same when we experience the growth of Divine Love in our hearts as we let the husk of the ego drop away and like seed we die to self that we may fulfill the destiny that is our true meaning, that the potential of life within us may come to fruition.
Our guardian angels will be present during the time when our souls will exit this world and abandon the material body. They will be there at the moment to offer us solace and support during that transition and then help us adjust to the realms of the spirits when our soul will be directed toward God. It will be at that point that the soul will become conscious of its eternal condition.
