It is said that to have learned even one letter of one word from someone demands respect and consideration for him. So a person who walks on the spiritual path recognizes the goal towards which he is traveling, and realizes that the wealth he will obtain is great indeed; he is well aware of the fact that there is no return he can make which is in proportion to what he has received from the teacher. Therefore the chela or mureed on the occult and mystical path is more grateful to his master than a person in any other walk of life can be to any other.
