Rainer Maria Rilke said this quote

Perhaps all the dragons in our lives are princesses who are only waiting to see us act, just once, with beauty and courage. Perhaps everything that frightens us is, in its deepest essence, something helpless that wants our love.

~ Rainer Maria Rilke

Therefore, dear Sir, love your solitude and try to sing out with the pain it causes you. For those who are near you are far away... and this shows that the space around you is beginning to grow vast.... be happy about your growth, in which of course you can't take anyone with you, and be gentle with those who stay behind; be confident and calm in front of them and don't torment them with your doubts and don't frighten them with your faith or joy, which they wouldn't be able to comprehend. Seek out some simple and true feeling of what you have in common with them, which doesn't necessarily have to alter when you yourself change again and again; when you see them, love life in a form that is not your own and be indulgent toward those who are growing old, who are afraid of the aloneness that you trust.... and don't expect any understanding; but believe in a love that is being stored up for you like an inheritance, and have faith that in this love there is a strength and a blessing so large that you can travel as far as you wish without having to step outside it.

~ Rainer Maria Rilke

For one human being to love another human being: that is perhaps the most difficult task that has been given to us, the ultimate, the final problem and proof, the work for which all other work is merely preparation.

~ Rainer Maria Rilke

To love is good, too: love being difficult. For one human being to love another: that is perhaps the most difficult of all our tasks, the ultimate, the last test and proof, the work for which all other work is but preparation...Love is a high inducement to the individual to ripen, to become something in himself, to become world for himself for another's sake, it is a great exacting claim upon him, something that chooses him out and calls him to vast things.

~ Rainer Maria Rilke
