(Just finished the translation of a talk on respect, confidence and patient, for today, my person came accross this question here)
To those seeing the danger in the world, and those who might possible develop deep regard for them, going to strive to get beyond that:
Such as to find understandig, that one prefers to be just a alms-beggar, at least, is not easy to understand, especially if coming from a fortunate seeming sociaty, but it's not different in traditional countries, when it goes to really leaving home, and not just from home to a certain known monastery.
One, if serious, must be clear, that he might no more have any relative support but needs at least relay totally on his actions and cause and effect, trust the existence of goodness and a still present supportive reputation of the three juwels.
It's merely seldom that even friends, relatives incl. parents will easily have understanding or tolerance in regard of going forth, since one/you is/are regarded as a part of their own, a source of "food" for the sense, an object for identification for them, which gets of it's nature lost by 'changing' the family, or inspire such.
My person guesses, that the most proper comparison, for others to understand, might be with a warrior, going out into battle for a good for himself and all his kind. The case that in this case the battle is not fought outwardly, without weapons, and the death rate in battle is merely very small, might be a picture for reasoning for others who possible would understand why someone becomes a soldier, for example.
It's how ever not really possible to make others understand clear and it's a bliss to be possible surounded by people who actually understand a strive for deathlessness, it is a bliss if one even grows up in a family where the three juwels are regarded and the going forth and renouncing the world is praised.
In circumstances of even slight appearence of the luck and fortune of avaliable condition for such, outwardly like inwardly, it is wise to take upon this seldom appearence, which will be faster gone as the most think, even generally in this world.
Is worthy to point out again, that it is not a matter of ones relatives or parents birth, culture, raw believe and it's totally independend of geography but a matter of faith, not only in such a way, but also in you as person or better your tendency, to make and follow aspirations serious and eager, while not losing an eye on virtue and harmlessness for those around you.
So if not having developed and shown certain attidutes of a warrier, even a noble one, in your sphere till today, such to start on, would be possible the best way to gain the, or more fearless leave from those your are related for now. To progress it lesser in a merely argumental way can never be that effective like a presenting by deeds.
In this way, those words might be not only an encouragement for those with merely open doors for now, but also for does, not having the conditions yet, not to search for the enemy of ones aspirations outwardly and in the cultur and sociaty, but in ones own qualities and the need to cause ones supportive gained effects by oneself and work on it.
Once leaded a soon heading discussion about the matter of condition (Nissaya), strong condition (upanissaya) and strong condition cause (upanissayapaccaya), it maybe gives additional food for wise thought: Why it is important to value our Conditions?
