They are not out of our scope. What is lacking is faith and courage, faith that nothing is impossible once something in us glimpses it as an ideal to be followed, and, the courage to go through whatever is needed to fulfil it.
As to marraige, in fact for anything in life, it is best not to make any absolute rules. Those who keep the ideal in front grow towards it through everything. Even a failed or painful marraige can make a soul marked for a higher life. Whereas those who may not be holding an ideal before them may actually end up having a seemingly happy married life, outwardly so to say, yet a life lived on the surfaces. No doubt trying to live an Ideal generates a kind of stress on the person who strives for it as well as on those who are near him. The chances of being misunderstood are high. Hence the qualifier does hold good for many that if you are striving for a higher life then think 50 times before you marry. And if one does, there should be a basic harmony of the ideal, a sympathy if not the same aspiration.
Affectionately,
