If human beings can understand their purpose of being then there is a good chance of heaven descending on Earth.
For every action thought or deed that any body does make sure that it aligns with these two universal goals.
1.Will I have a healthy body when the life atom or soul detaches from the physical body.
2.Will I be having a pleasant memory and a feeling of love and compassion for others based on all the interactions had with other human beings.
If my thought action and deeds all ensure and lead me to the above two goals then life will be bliss and always in happiness.
