If your husband is not interested in spiritual life, let him do as he pleases. I have given all of my disciple instructions to follow for making spiritual advancement, but if they do not have the desire to follow, then what can I do? Anyone who is unwilling to follow our regulated principles, you should not live or associate closely with such a person.
Letter to Kusa devi dasi, 3 February, 1975
Thank you for appreciating my books. Read them carefully and you will preach very nicely.
Letter to Candramukhi devi dasi, 2 February, 1975
It is not like the English language, "but, put'' with irrational difference in pronunciation, no principles. Sanskrit isn't like that. Therefore it is perfect. It isn't whimsical. English poetry has one line one inch long, next line 600 inches long. Sanskrit is not like that. There are strict principles, and it is so beautiful. Therefore in Sanskrit language not an ordinary man can become a poet. No other language of the world can be compared with it. No other language of the world is so perfect as Sanskrit. Any language near to Sanskrit language (like Bengali) is nearer to perfection.

Bhakti Devi is the expansion of Srimati Radharani.
Letter to Rukmini, January 31, 1969
Please continue your efforts in Krishna Consciousness with great determination. Yes, Patience is is a qualification in the successful execution of devotional service. So study our literatures, discuss philosophical points and problems with your God-brothers, and especially chant regularly sixteen rounds daily without offense and go on Sankirtana. We must always remember that chanting of Hare Krishna Mahamantra is our life and soul.
Letter to Madhusudana, 30 January, 1970
There is no difference between brahmacari, grhastha, vanaprastha, and sannyasi. Simply grhastha means that he lives outside the temple with wife, that is the only difference. Otherwise grhastha must follow the same regulative principles and remain fully engaged in the temple activities.

Regarding your question: Santa Rasa devotee has got unflinching faith in Krishna as the Supreme Personality of Godhead, but he has not developed the tendency to serve Him.
Letter to Bhagavan das, 28 January, 1970
So far as Deity worship is concerned, for the present you can have a Guru-Gauranga altar and later on when there are more devotees there and you have facility, Lord Jagannatha or Radha Krishna Deity may be installed. Only initiated devotees may tend the Deity or cook for Him, so for the present you can set up a very attractive Guru-Gauranga altar and that will be very nice.
Letter to Sukadeva, 27 January, 1971
There is no question of mythology when Krishna says: dehino 'smin yatha dehe kaumaram yauvanam jara/ tatha dehantara praptir dhiras tatra na muhyati [Bg. 2.13]. A baby grows to become a child, and a child grows to become a boy, and a boy grows to a young man, and a young man develops to middle age, and grows to an old man, and then what is next for the old man. The so-called mythologists don't know what will happen to the old man. Neither they believe in the next life, and even if they do believe they don't know what will happen to the old man or what kind of life he will get next. Therefore they are all fools and rascals.
Letter to Sri Batraji, 26 January, 1976
Regarding Deity worship: I am very much anxious to know how thing are going on, who is taking care of the Deities, whether regular performances are being executed etc. I hesitated to install the Deities when I was in Germany on this account. Anyway, when the Deities are now installed there cannot be any scope of neglecting Them; that will be a great offense.
