The direction is always upwards. Kundalini must rise to the top. In the head is where the bliss lies. Kundalini-Ananda; Kundalini-Bliss. The bliss of Kundalini. Pull up the breath consciously to the top of the head. Keep the breath there. Enjoy the stillness. Enjoy the bliss.
Keep the attention on this still bliss. You experience the perfection of being in this bliss. It is the sweetest experience. You cannot find a sweeter one anywhere. Sugar, honey, etc. do not come close to it. Nothing in the external world comes close to it. That is why it is easy to meditate on this bliss. It is the highest.
