I'd say, do your homework. Read the Karma Yoga website page attentively and ask questions. This program is an intensive learning and skill development experience, and not one of leisure in the field (although there is a magnificent land with time to integrate all the incredible teachings on it)!
Make sure you are wanting this kind of immersive experience and are ready to transform who you think you are. You need to know you want spiritual transformation and evolution. You need to know this transformation will happen if you put your heart into it and really seek the truth.
A day in the Karma Yoga Program starts around 6 - 6:30 am with a group meditation for around 50 mins. After that, there is a communal breakfast where everyone helps to prepare and clean up.
Once brekkie is over, there is usually a group connection where a Karma Yoga contemplation is proposed to guide the day. Teachers onsite are guides to support the discussion. Some specific tasks/projects are assigned to you for the day like cooking, working on the field, cleaning, preparing for retreats, etc. Lunch and dinner are also in the community, lots of time to exchange about self-awareness, mindfulness, new insights, astrology, Dharma, etc. There can be a sit in the evening too.
Some fun nights are in the schedule and you usually have one day off / week.
I was freaking out to the idea of traveling alone. I reached a point where I knew I would stay in a cage unless I met this fear, so that's what I did. Going into a meditation center to study and live with a community, I was also afraid to lose «myself» and be obliged to deal with people that I don't like and be stuck. All that happened and it became the best and most transformative experience of my life. Can't recommend it enough :)
Meet your fear. This is the only way you'll realize it's not true and it just holds you back from your true potential and life meaning.
The realization of mine and others' true potential that is far beyond our imagination. The power of meditation and conscious community is just unrealized unless you really get your teeth into it and taste through real experience.
