Love thy neighbour as thyself

The second most important commandent which Jesus said in reply to a person who asked what are the most important commandment said "Love Thy neighbour as thyself"
This commandment can only be understood if we realise that we are not this ego but all have the same Christ Consciousness that dwell within all of us. Jesus the human being who was crucified is only the garment that the Christ consciousness dwells .That is why He said 'I and my Father are one'In the same way all of us has has the same Christ Consciousness within us.As Jesus said the spirit of God dwelleth within you.At another occasion he says the Kingdom of Heaven is within you.
Once we have truly experienced the spirit of God within us or God Realization,we will automatically have love for everyone as the innermost of the soul is that of love.That is why Jesus said 'If you do not give food to the hungry, you are doing it unto me, if you do not clothe the naked , you are doing it unto me.Mother Theresa said that whenever she sees the poorest of the poor or the sick, what she sees is only the face of Christ.
God is love and he that dwelleth in love dwelleth in God and God in him.One who truly loves God automatcally love his fellow human beings.In Buddhism, insyead of love, they call it compassion.Compassion is a better term to use than love as compassion is unconditional love.
The Bodhisatvas are those who have already become enlightened but because of their compassion for their fellow human beings, they refuse to enter Nirvana but willing to be reborn again in order to help their fellow beings to become enlightened.
