"Intimacy: Love, Life & Giving or Egocentric Taking & Expiration"

Today, many confuse between intimacy in marriage, based on love, giving and life which are diametrically opposed to empty "sex", pornography and prostitution which destroyed the Beit HaMikdash. The practical importance of clarifying this topic in today's western society is obvious, especially for young adults.

Ein Aya

The Middle-Child & Anti-Tzni'ut Syndrome- Negative Attention

Although tzni'ut is for men just like women, Rav Kook deals here with the sources in Yishayahu and the Talmud which deals with the special problem of lack of tzni'ut in women's dress and actions, where it's not just a problem of midot and character traits, but also can include practical, social and national ramifications, as well, which caused the destruction of the Beit HaMikdash and exile from Israel. The class continues the previous one (Ayn Aya Shabbat vi, 29), and is a must for all educators and parents of high-school aged and young adults.
