Never Abandon the Way of the Holy Prophet (sa)
I would also like to tell you that there are many people who desire to attain these excellences by way of their own self-invented incantations and litanies. But let me tell you that if you adopt a method that was not practiced by the Holy Prophet (sa) then it is futile. Who could be more truly experienced in the path of those favoured by God than the Holy Prophet (sa)? In fact, he was a man in whose person all the excellences of prophethood reached their final limit as well. The path adopted by the Holy Prophet (sa) is the most effective and nearest way to God. To abandon this path and invent another – irrespective of the joy that it may bring – in my opinion, leads to ruin. This is what God has disclosed to me. By truly following the Holy Prophet (sa) one finds God; but one who does not follow the Holy Prophet (sa) – even after an entire life of striving – shall not be able to attain the ultimate objective.
