I am very glad to receive your letter dated May 26, 1968, along with beads, and I am so pleased that you are seeking for being initiated. So, after due chanting I am sending both your beads by separate first class post parcel. Receive it and chant without any offense. The 10 kinds of offenses are like this:
Blaspheming the Lord's devotee
Considering the Lord and the demigods on the same level—or assuming there are many gods
Neglecting the orders of the spiritual master
Minimizing the authority of the Scriptures
Interpreting the Holy Name of God
Committing sin on the strength of chanting
Instructing the glories of the Lord's Name to the unfaithful
Comparing the Holy Name with material piety
Inattention while chanting the Holy Name
Attachment to material things while engaged in the practice of chanting
So you follow those principles as well as the four restrictive rules, namely;
No addiction to indulgence in any form of intoxication, including coffee, tea and cigarettes
No illicit sexual relationships
Must be strictly vegetarian
No gambling
