Why is it necessary to filter the good impressions of the mind from the bad ones? Bhagawan lovingly reminds us today with appropriate examples.

Scientists, especially those belonging to the geological department, know this very well. When they prospect for gold, they find out the spot where gold is, then dig deep into the earth and find impure lumps of raw gold mixed with other elements. In this natural state, gold is found to be in the company of other impurities. At a later stage, they purify the impure mass and get pure gold from it. All natural laws will be like this. It is a natural law to answer calls of nature, to sleep, to feed, and so on. But by just following these laws of nature, we will not be able to go anywhere or reach any higher destinations. From the same heart, we find two emotions, one anger and the other mercy. Thus, we find it difficult to understand this nature, by which two contradicting emotions emanate from the same heart. Because the heart is the source of both good and evil, it is the bounden duty of students to understand how our ancestors were able to constantly focus their attention on good alone.
