In plain words
If man enquires well, with purity of citta, it becomes possible to recognise this truth. Though every man has in him the power to spread out, show forth and make blossom all the karaṇas within him, he thinks of himself as merely a weakling, a powerless man. How should man enquire into such a divine power? Of this very power the Kenopaniṣad: such a power, being mind to the mind, prāṇa to prāṇa, eye to the eye, ear to the ear and speech to speech, dwells within all things and makes them shine. For the light in a car to shine, for the horn to sound, for the wheels to turn or for the machine to run, current inside is essential. Only when we recognise the truth that the shining light, the moving wheels, the running engine and the sounding horn all depend on the current, do we understand the truth that all these karaṇas of ours also carry out their duties by the divine power of the Ātma, each by its own working. Not every flower that blooms sets fruit. Not every fruit that sets becomes ripe. But every ripe fruit must fall. This itself is the chief secret in being human. As soon as time, cause and duty come to an end, the body loses its power, loses its strength, loses its breath, loses its life, and comes to a stop. But what is the basis of this principle of life? That itself is the principle of the Ātma. Man makes his enquiry with the senses alone as his main point of view. There is a mind beyond the senses. This very mind the Upaniṣad has called Indra. That is, because he is the master of the indriyas, he has this other name, Indra. Indra means … the mind. So the Kenopaniṣad has said that only when the senses are joined to the mind and the mind is joined to the Ātma is this form, the mind and the Ātma blended together, the divine power. So today we are not joining our senses to the mind. We are not uniting the mind with the Ātma. The mind is placing them in what belongs to nature. So they divide the mind as one thing and the Ātma as another. The power of consciousness that pervades everything, in the mind, in the Ātma, in the body, in the senses, in the antaḥkaraṇa, in all things: that itself is the principle of Brahman.
