Sectoral heterochromia Heterochromia iridis is a condition in which the iris in one eye has a different color than the iris of the other eye or shows different colours within the same eye. The iris is the tissue of the eye that surrounds the pupil and imparts a color, whether green, blue, brown, hazel, grey, or other, to the eye. Iris color is the result of the pigment that is present in the iris. Brown eyes have large amounts of melanin pigment deposits, and blue eyes have a lack of melanin. Although eye color is inherited, the inheritance pattern is complex, with interaction of more than one gene. These genes interact to provide the full constellation of colors. Other genes may determine the pattern and placement of pigment in the iris, thereby accounting for solid brown as opposed to rays of color. Normally, the two irises of an individual are of the same color. In heterochromia, the affected eye may be hyperpigmented (darker or hyperchromic) or hypopigmented (lighter or hypochromic). Eye color is determined primarily by the concentration and distribution of melanin within the iris tissues.Text by medicinenet.comImage found on postgrad-premed.tumblr.com/

Compassion hurts. When you feel connected to everything, you also feel responsible for everything. And you cannot turn away. Your destiny is bound with the destinies of others. You must either learn to carry the Universe or be crushed by it. You must grow strong enough to love the world, yet empty enough to sit down at the same table with its worst horrors.
Andrew Boy (via silentsigh57)

You know how this is:
if I look
at the crystal moon, at the red branch
of the slow autumn at my window,
if I touch
near the fire
the impalpable ash
or the wrinkled body of the log,
everything carries me to you,
as if everything that exists,
aromas, light, metals,
were little boats
that sail
toward those isles of yours that wait for me.
Pablo Neruda (via observando)

There’s so much more to life than finding someone who will want you, or being sad over someone who doesn’t. There’s a lot of wonderful time to be spent discovering yourself without hoping someone will fall in love with you along the way, and it doesn’t need to be painful or empty. You need to fill yourself up with love. Not anyone else. Become a whole being on your own. Go on adventures, fall asleep in the woods with friends, wander around the city at night, sit in a coffee shop on your own, write on bathroom stalls, leave notes in library books, dress up for yourself, give to others, smile a lot. Do all things with love, but don’t romanticize life like you can’t survive without it. Live for yourself and be happy on your own. It isn’t any less beautiful, I promise.
