What does Chapter 10 teach about the simplest and most effective 'Sadhana' or spiritual practice?

Chapter 10 presents a very accessible yet powerful spiritual practice (Sadhana). It states that the 'best of all means' is to 'always remember with a heart full of love Him who is devoted to the welfare of all people.' This practice of constant, loving remembrance of the Guru costs nothing but yields immense spiritual fruit. As Chapter 10 describes, by His mere remembrance, the 'knot of birth and death is untied.' The chapter emphasizes that this simple Sadhana allows one to cross over the three types of miseries and attain liberation (Moksha) effortlessly, as the Sadguru himself places knowledge in the devotee's palm.
