I like most religions once I get to know them...
Off the top of my head, aside from just loving a variety of music, art, and so forth...
Judaism- the history, the depth of discussion about everything
Islam- the art and architecture of mosques (all that geometric stuff is so beautiful), the way prayer is called many times a day, the structure of it all appeals to me as it does in Judaism- the integration of daily life with spiritual life
Indigenous/Animistic/Shamanistic- the often lack of boundaries between human and nature, and human and the spiritual realm. Great, interesting myths and legends, lots of cool ties between places and spiritual stuff.
Hinduism- the complexity of it all, and yet merged with simple paths such as devotion to a god/dess, the interesting variety of portrayals of god/desses (those many-armed ones to remind us that the Divine always has a hand ready for us when we need it), yoga and a spirituality that can so encompass the body as well as the soul
Buddhism- meditation, compassion for all beings, peacefulness. Zen art is particularly appealing to me in its simplicity. The dedication of the monks and nuns, and their purposefulness, is amazing to me.
Taoism- the Tao Te Ching is one of my all time favorite texts. It is gorgeous, poetic... The non-resistence, the learning from nature.
Universalism- the open-mindedness and excitement about other religions.
New Thought- the focus on thinking positively, on changing one's perspective, and on gratefulness.
There's a few...
