Is it okay to earn money through interest by giving money on loan to others?

[Shri Manikanta asked: Padanamaskaram Swami, Is it okay to earn money through giving interest to other people? By, Manikanta]

Swami replied:- It is quite justified, provided justified interest is collected. Collecting interest on principle is called “Kusiida”. This word means that in this line of business, sometimes even the principle may be lost. You have to be very careful about this point.
