“Every human in the world is a potential customer (for taking up Krishna Consciousness). There are no restrictions due to caste, color, creed, gender or age. Everyone is a potential customer. Whoever has the proper ‘money’ can buy the goods.
The currency is described as being the pure desire to serve the Lord. Any mixture with other motives create a counterfeit situation. Counterfeit money means that when the customer chants the holy name of Krishna, he will not be able to experience the same transcendental bliss, or the same realization, as does the pure devotees, who has no mundane motive for chanting.
To enter deep into the real ecstasy of Krishna consciousness, one should be sure that his motives are pure, thus avoiding counterfit money, which only resembles money but has no actual purchasing power!.”HH Jayapataka Swami From the book: Sri Godruma Kalpatavi
