Sahasrara

Do not go to the garden of flowers!
O Friend! go not there;
In your body is the garden of flowers.
Take your seat on the thousand petals of the lotus,
And there gaze on Infinite Beauty.
- Sant Kabir

The Garden of Flowers within refers to the Subtle Body with it's flower-like Chakras. The Lotus of a Thousand Petals is the Sahasrara Chakra at the crown of the head, where the yogi achieves Self-realisation. In meditation, this is the best place to put one's attention, as it is above the ego and superego (the mind).
