In Fifth Kriya the devotee mostly feels divine sensation in the cerebellum. You are gradually coming close to the pineal gland and are trying your utmost to enter into it. As lightening strikes, accompanied by thunder and rain, so do sparks fly up from your coccyx to illuminate your whole world with powerful sound, light, and vibration. Water (tears) will come, as an expression of your deep love for God. You cannot stop crying, because you are in the living presence of God.
This fifth level of samadhi is called sattapatti samadhi. Satta means soul. Patti meansappearing. Soul is appearing and trying to enter into the pineal gland. That means you are near nirvikalapa samadhi.
With the Fifth Kriya practice you may also attain the sixth level samadhi, called padartha bhavini samadhi. That means you are almost merging in wisdom. At this stage you have no sense of the universe. You are feeling that the door of God is open part way, but you cannot yet enter. Through your meditation you are seeing the power of God in each human being and in all plants, animals, trees – in the five gross elements underlying all physical existence. You are absorbed and merged in God, in higher cosmic consciousness.
