This invocation is from the Orphic Hymns, for those who like historical accuracy, but have been updated just a tad, for those who like ritual with modern applications.

Invocation to the God

Hear Our Prayer, O best and Many-Named God.
Fine-haired, solitary, and full of lovely song;
Many shaped and noble nurturer of all,
Maiden and youth in one, unwithering bloom, O Adonis
You vanish and grow again in the fair seasons’ turn.
Kurnunnos, Pan, Myrddhn, two horned Spirit of growth and blooming;
Much loved and wept for are you,
O Fair and Youthful Hunter of the luxuriant mane.
Desire is in Your mind and You come to the Goddess in reverence and respect,
in sensuous joy is your desire fulfilled
You are the seed planted in the depths of the Underworld
That springs forth, the Green God, that we may sustain our lives.
You sacrifice Yourself in gentleness when you are grown.
Come Kind-Hearted One, Come Blessed God,
and bring much joy to all.
