Is rising from prostration and sitting between the two prostrations the same thing?

Question:
He says: Honorable Shaykh, may Allah grant you success. In the pillars of prayer, the author (may Allah have mercy on him) mentioned prostration, rising from it, and sitting between the two prostrations. Is rising from prostration and sitting between them the same thing?

Answer:
No. One can rise and then prostrate continuously, so both are required: rising and sitting. If he rises and prostates immediately, leaving out the sitting, his prayer is invalid, because he left a pillar. Yes.
