SB 7.15.65, Translation and Purport

When the ultimate goal and interest of one's self, one's wife, one's children, one's relatives and all other embodied living beings is one, this is called dravyadvaita, or oneness of interest.

The actual interest of all living entities—indeed, the goal of life—is to return home, back to Godhead. This is the interest of one's own self, one's wife, one's children, one's disciples and one's friends, relatives, countrymen and all humanity. The Kṛṣṇa consciousness movement can give directions for management by which everyone can partake in Kṛṣṇa conscious activities and reach the ultimate goal, which is known as svārtha-gatim. This objective of everyone's interest is Viṣṇu, but because people do not know this (na te viduḥ svārtha-gatiṁ hi viṣṇum (SB 7.5.31)), they are making various plans by which to fulfill so many concocted interests in life. The Kṛṣṇa consciousness movement is trying to bring everyone to the highest interest. The process may be differently named, but if the aim is one, people should follow it to achieve the ultimate goal in life. Unfortunately, people are thinking of different interests, and blind leaders are misleading them. Everyone is trying to reach the goal of complete happiness materially; because people do not know what complete happiness is, they are materially diverted toward different interests.
