In plain words
“Churn and churn, and fire is born in the wood; churn and churn, and ghee is born in the curd; churn and churn, and the tattva is born in the body; listen, O valiant son of Bhārata!”
When there is friction between stick and stick, fire springs forth. When you churn the curd well, butter is born in it. In the same way, only when form and name rub against each other in our heart does divinity become manifest. God is everywhere. Just as there are no rays of the sun without the sun, so without God this world itself does not exist.
The belief of the young people of today is that this world is lasting, that this alone is the main thing. This is a great mistake. “Anityam asukhaṃ lokamimaṃ prāpya bhajasva māṃ,” said the Teacher of the Gītā. That which undergoes no changes and no alterations, that which is Satya and eternal, is the one divinity, and that alone. Forgetting such divinity, the young man of today scrambles in many ways after happiness in worldly things. First of all he studies, thinking there is happiness in studies. Next he works at a job, thinking a job will bring him happiness. Then he marries, thinking that if he marries, happiness will come. Then he imagines that if sons are born to him, he will find happiness. But in the end he cannot find happiness in anything. In everything, nothing but unrest! Nothing but unrest! Nothing but unrest! What is the cause of this unrest? Desires alone! Because purity of heart is lacking, many diseases come upon man today. However many sādhanas we do, however many holy places we go round, however many pūjās we perform, without purity of citta there is no gain. We do all these only for the satisfaction of the mind. But to satisfy the mind is beyond anyone's power. “Cañcalaṃ hi manaḥ Kṛṣṇā pramādi balavaddṛḍhaṃ,” said Arjuna. The mind is exceedingly restless. Who can satisfy such a mind? Who can hold it back? Only through the influence of the mind does what is called saṃsāra come upon man. You can cut the sky into pieces, you can tie up the wind in a bundle, you can drink the ocean in a single gulp. But the mind you cannot hold steady. Restlessness is natural to the mind. This is the law of nature. So there is no gain in trying to curb the mind. We must turn the mind towards God. This very thing they called Bhakti.
