As you can see it is not actually seven lines long. On the other hand, there are seven syllables in each line.
It means,
In the northwest of the land of Orgyen
In the heart of a lotus flower
Endowed with the most marvellous attainments
You are renowned as the Lotus-born
Surrounded by many hosts of dakinis (female Woodwights)
Following in your footsteps
I pray to you: come and give me your support.
It sounds suitable to me!
