Attend this annual day-long celebration of the enlightenment and life example of Milarepa, one of the great Kagyu Lineage forefathers, who is famous for his profound songs of realization. The celebration is an all day guru yoga practice, which includes chanting the Milarepa Sadhana and reading the songs of the lineage fathers in The Essence of the Ocean of True Meaning, known to us as the The Rain of Wisdom. These songs are the direct personal voices of the lineage holders, sharing their experiences of the path, practice, and realization.
Everyone is encouraged to participate wholeheartedly in this inspiring celebration of awakened mind passed down to us directly from Tilopa, Naropa, Marpa, Milarepa, Gampopa, and the rest, in the unbroken transmission from teacher to disciple, right to the present day. It's always a powerful day, and a lot of fun. There is no charge.
The book is rare and hard to find, but after many years, it seems that Amazon has copies it is selling: http://www.amazon.com/The-Rain-Wisdom-Essence-Meaning/dp/1590309014/ref=sr_1_1?ie=UTF8&qid=1394421965&sr=8-1&keywords=rain+of+wisdom
There are also used copies you can buy at the above link. It would be best if you could buy the book if you plan on attending. Another option is to just sit and soak in the readings from others. Or, we can also share books.
