In plain words
If you wish to experience this shining principle, what must you do? Follow Satya. They gave light the name Sat. All the rest is bound to perish. ‘Yad dṛśyaṃ tan naśyam’: all that we see must perish.
Asthiraṃ jīvanaṃ loke asthiraṃ yauvanaṃ dhanam asthiraṃ dārā putrādi satyaṃ kīrti dvayaṃ sthiram
All things are bound to perish, bound to waste away. All are merely bound to vanish. But what stands is Satya. That is why they called that Brahma, whose form is vast, Satya. From that Satya Jñāna came forth. This Jñāna and Satya pervade all. That is why the Veda said, ‘Satyaṃ, jñānaṃ, anantaṃ Brahma.’
The Avatāras have come to show the unity in diversity and to make you turn divinity itself into your own form
What must man attain today? Satya itself is Jñāna. Jñāna itself is the infinite. The infinite itself is the form of Brahma. There are only names, but the divinity that pervades all is one. That itself is Sat. If you wish to attain such a One whose form is Satya, what must you do? You must keep following Satya. What is Satya? Satya is that which does not change in the three times. Any substance may change, but Satya cannot change. That which stays one in past, future and present is Satya itself. Why does God come down as an Avatāra? When you put this question to yourself, the essence of this Avatāra, spiritually, is that He comes down to show the unity in diversity, to make you recognise the unity that is in diversity, to awaken you to the divinity in that unity, and to make you turn that divinity itself into your own form. This alone is the goal of life. The human form that appears as many you must believe to be one. Bodies may be different. Countries may be different. Men may be different. The ways men conduct their lives may be different. But the unity in them all is one. That alone is the principle of the Ātma. That is just what they called conscience.
