There are two types of knowledge: the doctrine of the mind and the doctrine of the heart.
The doctrine of the mind is for those who are contented with spiritual theories and beliefs. The doctrine of the heart is for those who put into practice the teachings that they receive and gradually experience them in themselves.
The vast majority of members from spiritual schools belong to the doctrine of the mind. Initiates and masters from the Universal White Brotherhood belong to the doctrine of the heart.
The mere followers hold changeable concepts because their knowledge only belongs to the intellect, which is something superficial and worthless. That knowledge strengthens the mind, and the mind is the refuge of desire: it thinks, analyses, draws conclusions and eventually is wrong. The mind will never get to know the Truth.
Those who thoroughly practise the teachings given to the world by the great Masters of Humanity will experience and develop spiritual capabilities unknown by the common man. Those people always listen to and heed the voice of the Internal Master. It is the doctrine of the heart that opens the doors to true wisdom.
