70 kopeks

The Tzemach Tzedek once said to his son the Rebbe Maharash: For one who helps another Jew in his livelihood, even if he helps him earn a mere 70 kopeks (a low-value Russian coin) on a calf, all the gates to the heavenly chambers are open for him. Years later the Rebbe Maharash added: one ought to know the route to the heavenly chambers, but actually, it is not crucial. You only need the main thing: to help another wholeheartedly, with sensitivity, and to take pleasure in doing a kindness to another.
