It is a noble feeling, but it is still a feeling

Ontem, após meu fiasco em Cálculo 3, decidi ler um pouco mais de Cristianismo Puro e Simples porque C.S.Lewis sempre tem algo bom a ensinar de maneira simples para um cérebro cansado.
Li uns 4 capítulos, porém os que mais me chamaram atenção foram os relacionados a relacionamentos. Teve um trecho em particular que gostei bastante porque me lembrou muito algo que eu mesma escrevi há algum tempo aqui, então trago para os caros leitores de forma muito mais eloquente, o que eu havia tentado passar aquele dia.

"What we call 'being in love' is a glorious state, and, in several ways, good for us. It helps to make us generous and courageous, it opens our eyes not only to the beauty of the beloved but to all beauty, and it subordinates (especially at first) our merely animal sexuality; in that sense, love is the great conqueror of lust. No one in his senses would deny that being in love is far better than either common sensuality ir cikd sekf-centredness. But, as I said before, 'the most dangerous thing you can do is to take any one impulse of our own nature and set it up as the thing you ought to follor at all costs'. Being in love is a good thing, but it is not the best thing. There sre many things below it, but there are also things above it. You cannot make it the basis of a whole life. It is a noble feeling, but it is still a feeling.Now no feeling can be relied on to last in its full intensity, or even to last at all. Knowledge can last, principles can last, habits can last; but feelings come and go. And in fact, whatever people say, the state called 'being in love'usually does not last. (...)
But, of course, ceasing to be 'in love'need not mean ceasing to love. Love in this second sense - love as a distinct from being in love' - is not merely a feeling. It is a deep unity maintained by the will and deliberately strengthened by habit; reinforced by (in christian marriages) the grace which both partners ask, and receive, from God. They can have this love for each other even at those moments when they do not like each other;  as you love yourself even when you do not like yourself.(...) 'Being in love' first moved them to promise difelity: this quieter love enables them to keep the promise. It is on this love that the enfine of marriages run: being in love was the explosion that started it."
