Generally it is Christians and Buddhists who seek out converts, and none of the other main religions (Judaism, Hinduism, Islam.)
although Judaism doesn't seek converts, you can read the Torah. you can walk into a synagogue or a Jewish bookstore and ask.
In the early Roman era, Judaism was a proselytizing religion. There are numerous stories of converts from among the pagans of the Roman empire, and several of these converts achieved high status as scholars in early rabbinic Judaism. Since then, however, Jews largely ceased to proselytize, in part because under both Christian and Islamic rule, converts to Judaism and those who aided their conversion were frequently subject to the death penalty. Even as recently as 1848, Warder Cresson was declared insane in the United States for converting to Judaism. Starting in the 20th century, the number of converts to Judaism increased significantly, but only recently have some movements within Judaism begun to discuss the possibility of serious programs of proselytizing. The dominant rule continues to be that Jews not only do not seek converts but warn potential converts are warned of the risks they are taking. That said, all major branches of Judaism welcome converts once they complete the rather daunting process of conversion.
Historically, Jews did seek converts to Judaism. However, this practice stopped, mainly due to Christian and Muslim persecution.
Yes, the State of Israel recognises both Conservative and Reform converts to Judaism for immigration purposes.

No. It is part of Buddhism. Judaism does not seek "spiritual enlightenment".
Judaism has always allowed conversion. Moses married the daughter of a Midianite Priest. Ruth, the ancestor of King David, was a Moabite. Judaism does not actively seek converts. There are two reasons Jews have not traditioinally sought converts: First, Judaism does not hold that you need to be Jewish to be "saved." To quote one medieval commentator, "the righteous of all nations have a place in the world to come." So, the only obligation Jews have is to help people not sin. There is no need to convert them. Second: Under Christian and Islamic rule, until fairly recently, converts to Judaism were subject to the death penalty, as were any Jews who took part in the conversion.
