The Highest method of worship
It is said that great personalities almost always accept voluntary suffering because of the suffering of people in general. This is considered the highest method of worshiping the Supreme Personality of Godhead, who is present in everyone’s heart.
PURPORT
Here is an explanation of how those engaged in activities for the welfare of others are very quickly recognized by the Supreme Personality of Godhead. The Lord says in Bhagavad-gita (18.68–69), ya idaˆ paramaˆ guhyaˆ mad-bhaktev abhidhasyati. .. na ca tasman manuyeu kacin me priya-kttamaƒ: “One who preaches the message of Bhagavad-gita to My devotees is most dear to Me. No one can excel him in satisfying Me by worship.” There are different kinds of welfare activities in this material world, but the supreme welfare activity is the spreading of KŠa consciousness. Other welfare activities cannot be effective, for the laws of nature and the results of karma cannot be checked.
