First of all, an excerpt from http://www.rocor.org.au/news/?p=24 (emphasis is mine)
Father James Carles says: "Last year, some may recall, I spoke to you about what Saint Seraphim of Sarov called the 'necessary means' of Christian life: the various spiritual disciplines that our Holy Orthodox Church alone preserves in fullness. We discussed then how we can put God at the center of our lives and protect our life-giving relationship with Him by:
- Reading the Holy Scriptures every day;
- Saying morning and evening prayers;
- Praying in church as often as possible, especially on Sundays and feast-days;
- Receiving Holy Communion as often as possible;
- Making the home like a “family church”, with icons in every room;
- Following the church calendar of fasts and feasts; and
- Helping the poor and needy, showing love and kindness to all around us, and praying for others.
Secondly, here are some "works of mercy" we are called to practice from the website located at http://www.orthodoxnet.com/worship/occasionalprayers.html (incidentally, there are many helpful prayers at this page):
