Love; a luxury or a necessity

The experience of love is either a necessity or a luxury. If it be a luxury, it is expendable; if it be necessity, then to deny it is to perish. So simple is the reality, and so terrifying.
Ultimately there is only one place of refuge on this planet for any person -- that is another person's heart. To love is to make of one's heart a swinging door. ~ Howard Thurman
