I don't think we're talking about the same thing, because according to what is classically meant by spiritual enlightenment, you don't "achieve benefits through enlightenment". You certainly don't "achieve" anything, and there are no "benefits" to spread.

Perhaps that may sound somewhat paradoxical, but that kind of paradoxical understanding is somewhat representative of enlightenment as a whole.

Can you really think of anyone you believe to be truly enlightened spiritually, who is busy trying to "spread it to as many people as possible"? I think the answer is no. The enlightened may help you out if you seek their assistance, but they are almost the exact opposite of "evangelicals" who seek to spread a message.

Of course there is no "benefit of enlightenement", it is itself its own benefit.

It is a real gift, and I know many people who do their best to help as many others achieve it as they can.

It is considered a service and a sacrifice to forgo one's comfort to help others achieve enlightenment.

You may be imagining someone being pushy or insistent, but this does not have to be the case.

This is said like someone who had perhaps not achieved the type of enlightenment crazygringo has :)
