To achieve purity of mind, one should cultivate constant awareness by being mindful all the time. One should remain always aware of one's thoughts.
Rama SwamiWhat Jesus meant was that whoever is attached to the worldly life and this earthly body will lose them in death. But whoever lets go of attachments to this worldly life and this earthly body and identifies with the permanence or God-consciousness that Jesus represented, will never die.
Rama SwamiGod is One. There cannot be two or more. For if there were two God's who created them? There must have been someone who came before them. Therefore God is only One - One Final Absolute Existence. Everything else is a manifestation of Him.
