As soon as the child is born ; immediately there is milk in the breasts of the mother and one minute before, there is no milk. As child is born, immediately who supplies the milk? He does not see that one Supreme (person) is supplying all the necessities of the others. So our duty is only to become Krishna Conscious. Other things will be supplied by Krishna.
Fate can be changed by Krishna Consciousness. Krishna says, "I shall give you protection from all the resultant action of your sinful life.” That is fate changed. When you surrender to Krishna, He takes charge of squaring up all your sinful activities and their reaction. Surrender to Krishna; then your fate is changed.
A person who does not disturb or cause painful action in the mind of any living entity, who treats everyone just like a loving father does his children, whose heart is so pure, certainly very soon becomes favoured by the Supreme Personality of Godhead.
One who performs his duty without attachment, surrendering the results unto the Supreme Lord, is unaffected by sinful action, as the lotus leaf is untouched by water.
