In the land of Uddiyana’s northwest border,
On the pistils of a Lotus flower’s stem,
You attained the marvel of the supreme siddhi,
And became known by the name the Lotus-Born.
With surrounding circles of many dakinis,
In your footsteps I will reach accomplishment.
Please approach in order to bestow your blessings.
Guru pema siddhi hung.
There is a wonderful explanation of these seven lines by the great Mipham entitled White Lotus: An Explanation of the Seven-line Prayer to Guru Padmasambhava. It gives many levels of explanation to inspire you as you chant this deep link to Padmasambhava's heart and realization.
Just recently, there is also The Sole Panacea: A Brief Commentary on the Seven-Line Prayer to Guru Rinpoche That Cures the Suffering of the Sickness of Karma and Defilement, by Thinley Norbu Rinpoche.
