Here is the Podcast of the Luminous Mysteries of the Rosary, which are ordinarily prayed on Thursdays in Ordinary Time, but as with any of the mysteries, you can pray whichever one the Spirit is leading you to pray.
Many Catholics have difficulty remembering the Luminous Mysteries as they are fairly new – instituted by Pope John Paul II.
Moving on from the infancy and the hidden life in Nazareth to the public life of Jesus, our contemplation brings us to those mysteries which may be called in a special way “mysteries of light”. Certainly the whole mystery of Christ is a mystery of light. He is the “light of the world” (Jn 8:12). Yet this truth emerges in a special way during the years of his public life, when he proclaims the Gospel of the Kingdom. In proposing to the Christian community five significant moments – “luminous” mysteries – during this phase of Christ’s life, I think that the following can be fittingly singled out: (1) his Baptism in the Jordan, (2) his self-manifestation at the wedding of Cana, (3) his proclamation of the Kingdom of God, with his call to conversion, (4) his Transfiguration, and finally, (5) his institution of the Eucharist, as the sacramental expression of the Paschal Mystery.

I like them – they are wonderful to meditate on:
