"You shall love your neighbor as yourself." Matthew 22: 37-39" Is an invitation, to love yourself at first place.
Without self-love one does not know love, there is then a void that one 'tries' to fill by 'thinking' that one loves others.
Loving yourself is the key to feeling love for others. There is then no more void that 'must' be filled.
Really loving yourself can be felt in every fiber of the body, every thought, every action. You are love yourself! This love flows through you and fills the space that you occupy.
This Love comes from the Soul and radiates to every living being, who is free to accept or not to accept this love.
