You can get any ordinary candle and take one per day to be consecrated: SIXTH to the Father, SATURDAY to the Son, SUNDAY to the Holy Spirit.
The promises of the Pentecost Candles tells us: "At the most difficult moment of life, one should light the candles and the miracle will happen."
The candles are God's promise that was raised in the heart of Father Moacir Anastácio, were blessed and consecrated the Holy Trinity, are light and hope for the difficult moments, where God never abandons us.
If you do not need it, you can, for charity, kindle it to someone you need. To light the candles for a brother in need is a great blessing, it is to praise God who also lives in the heart of the brother! It is an act of great generosity and it is also a Christian duty to be charitable and to intercede for others.
May God continue to bless you and enlighten you always!
