Sai advises that those who wish to follow the path of spirituality, should keep away from 3 things, first is kanchan, second kamini and third kirti.
Kanchan means wealth. One should earn enough to run his household comfortably and lead a decent life. It should not happen that you go on accumulating money and towards the end you face serious health problems due to such futile obsession. We should not be blindly after money, but we should have it as per requirement.
Second is Kamini, means another woman. When a man runs after or befriends such a lady, not only he ruins his home, but also it adversely affects his health. That is why not only one should stop even thinking of another woman but also completely remain aloof from such a vice. Such misadventure can even result in other serious problems like it can lead towards the doors of a jail, so one has to take extra precaution of not indulging in it.
The third thing that is a big obstacle is Kirti, which means fame. A person who has a big name and reputation is bound to be maligned and disgraced. He is likely to fall in such a pit where he can never be found again.
When Sai were giving this knowledge, one devotee asked as to how one can save himself from these vices? Sai said that he should attend and involve himself in Satsang, where one can regulate his mind and thoughts towards refinement!
To conclude, kanchan, kamini, kirti are impediments towards spiritual advancement and will not allow a devotee to achieve refinement!
