The scriptures talk about the same horse. It’s true that the Bible is talking about the coming of Christ. The Bhagavatam says that the Kalki Avatar will be coming. And, of course, the Koran talks about the return of Mohammed. Here we see the unity, the similarity. Even if it is three corners of the world, yet, you see the similarity of the scriptures. They are all talking about the coming of one being, riding on a white horse, bringing justice, peace, uplifting humankind. And here, you see that everyone talks about the same personage in a different way, but actually it is One. The Muslims call Him Mohammed; the Hindu call Him the Kalki Avatar and the Christians call Him the return of Christ, Jesus. But actually, It is the same One.
And when will He come? When everybody really awakens this pure Love inside of them. When everybody realises this pure Love, then He will come. Actually, They do come, when you realise your Self. They awake within your heart. Not as big, to be seen in the outside. But They do manifest themselves, within the heart of man. You can call it Realisation, God-Realisation or the attainment of the Lotus Feet of the Lord.
They reveal Themselves – the Lord reveals Himself to each person who is completely surrendered to Him. The Lord is not bound by Time the way people think about it. People think, ‘Okay, this is the time for Dwarapa Yuga, or Satya Yuga, or Treta Yuga or now, Kali Yuga’. But, the Lord is not bound by any time as humans think. He is beyond Time, He is the Master of Time. He is the Lord of Manvantara, He is the Lord of Time Himself. So that’s why He manifests Himself within the heart of man.
White is purity. The horse symbolises one single-pointed mind. The focus of the mind. When the mind is focused, when the mind is under control. That's what the Gita says, ‘Control the senses’. And the senses, in the Bhagavad Gita, when you see Krishna riding in the battlefield, He is holding with His hand, five horses. Each horse symbolises one sense. So He said, 'Control the senses’, but the last is the mind! The mind is not counted as one of the senses. Because it is the master, because everything is the mind.
So here, you see Kalki Avatar riding over the mind, itself. When the mind gets one single-pointed towards one goal – towards one aim – then the Lord reveals Himself. So the horse symbolises single-pointed mind, focus, and the control of the senses.
