Will Kalki use sword like knowledge or knowledge like sword?

[Ms. Thrylokya asked:- Swami, it is said that Kalki, the last incarnation of God, will use sword to bring spiritual reformation in the world. Will He use sword like knowledge or knowledge like sword? Kindly clarify. At Your Divine Lotus Feet, Thrylokya]

Swami replied: Before the final incarnation of Kalki, who will use sharp knowledge like a sharp sword, God will incarnate as several preachers to preach the sharp true spiritual knowledge, which is like the sharp sword. Gita mentions this knowledge like a sharp sword (hṛṣṭaṃ jñānāsinā'tmanaḥ). Spiritual knowledge can bring some permanent reformations but the sharp lightning sword of Kalki will bring temporary reformations in the case of all souls.
