Monks and nuns are rare to come by these days because it is not easy to be one as there are many restrictions placed upon them and most people these days would not want to let go of their own desires and entertainment but in reality these restrictions help to prevent them from creating more misdeeds and also to give them less distractions to worry about so that they can focus purely on the Buddha's teachings. therefore, vows and percepts are the very foundations of Buddhist practice, as the Buddha had taught as the benefit is two fold: to free us from distractions and also to prevent us from gathering more negative karma.
The other reason why monks are hard to come by these days is because not many people understand what a monk should do and should not do. There is a kind of fear and misunderstanding on what entails of becoming a monk due to cultural and social perceptions. Due to these two main factors, many people do not see the point of become a monk. Also, there is also a trend among new age Buddhists that Buddhism does not require any form of belief or commitment, and that it's a very personal practice (right......why does that sound so familiar with the protestants?) when reality is that a lot of dedication, study and hard work as well as commitment is necessary for real Buddhist practice and many do not understand or wish to engage in anything that requires commitment.
The sangha is to be respected and is worth of the respect of the laity because they are of the following quaities:
They are the Blessed One's disciples who have practised well,
Who have practised directly,
Who have practised insightfully,
Those who are accomplished in the practice;
That is the four pairs, the eight kinds of noble beings,
These are the Blessed One's disciples.
Such ones are worthy of gifts, worthy of hospitality, worthy of offerings, worthy of respect;
They give occasion for incomparable goodness to arise in the world
I chant my praise to this Sangha,
I bow my head to this Sangha
Hence, since they are much more committed in the Dharma as compared to ordinary people, they should be given respect for being dedicated in their Dharma practice alone. However, some lay people have developed an idea that since a monk receives alms from the people, it is their purity that 'feeds' them and keeps them alive and therefore in addition to the vinaya, a monk must also conform to the social norms as defined by the laity. If a monk goes against that, they are impure and that the laity are the guardians of the monk's purity. What do you guys think about that stance? It is widely popular in several countries.
