March 2 1970 letter Bhagavan
The pradhana is the ingredient part of material energy. Yes, the Maya is covering all the material energies. Therefore one who is materially advanced, covered with riches, covered with learning, covered with fame or covered with any material opulences, is understood to be covered with Maya. Srila Bhaktivinode says, jada vidya saba mayar baibhava “the material opulences are expansions of Maya’s influence.” As such, according to Vedic process, one voluntarily renounces the material opulences.
The Goswamis left their government service, and there are many other instances. Bharata Maharaja left his kingdom and Lord Buddha left his kingdom—these are all different attempts to get out of Maya’s influence. But our philosophy is that things employed in Krsna’s service have no more influence of Maya. Therefore it is called cinmaya or spiritual; spiritual means complete knowledge. One who can follow the instructions of Isopanisad can understand that nothing belongs to Maya, but everything belongs to Krsna. This knowledge is Krsna Consciousness. 
Regarding the end of devotees of Lord Jesus Christ, they can go to heaven, that is all. That is a planet in the material world. A devotee of Lord Jesus Christ is one who is strictly following the ten commandments. Now just like in the commandment “Thou shalt not kill” this is a moral instruction for the sinful man. Similarly Lord Buddha also emphasized ahimsa paramadharma “the highest religion is nonviolence.” So these instructions are for the sinful men. When one is pious, instead of being sinful, he is promoted to the higher planetary systems like Janaloka, Mahaloka, or Tapaloka and they are above the planet Svargaloka. So persons who are cleansed of sinful life become eligible for spiritual life. From the instructions of Lord Jesus Christ we find that the stress is given to make men free from sinful life—such as “Thou shalt not kill” “Thou shalt not covet”—like that. Therefore the conclusion is that the devotees of Lord Jesus Christ are promoted to the heavenly planets which are within this material world.
 
Nov 1 1970 letter Satyabhama
Regarding Brahmananda, he is actually surrendered soul, but Maya is so strong that on account of association he has even fallen down. So these two things are always side by side—Maya and KrsnaKrsna is service and Maya is sense gratification, so every moment we are prone to be subjugated by either of them. Our duty is therefore to be very, very careful. The poison is personal ambition. So everyone has the chance, therefore one should not be complacent. Doubts may come about, but one should be firmly fixed up that there cannot be any doubt on the Spiritual Master or Krsna.

Now you are placed in a responsible post, so I may request you to very carefully execute the regular program as you have learned it in Los Angeles. If the regulative principles are strictly followed there is no chance of maya’s dangerous influence to come in and cause some havoc. Maya is always peeping, ready to take advantage of our any lapse from devotional standard, so everyone should be continuously engaged in either chanting, studying or working and preaching. This full schedule will save you from engagement elsewhere. Maya and Krsna are always side by side. Either one is serving Krsna or he is serving Maya. Please manage the affairs of your temple in close cooperation with Karandhara and your Godbrothers and Krsna will give you the good intelligence to progress nicely.

Nov 29 1970 letter Gargamuni
Maya is very strong and she can victimize anyone of us at any moment. We shall therefore always keep ourselves vigilant and this is only possible by rigid engagement in Krishna’s service. Certainly maya attacked you a few months ago and now again you are determined to serve Krishna; that will keep you secure. I shall always pray to Krishna for your protection. Side by side you also remain always engaged in Krishna’s service and thus there will be no chance of falldown. I think your program is going on nicely. You also follow the regulative principles, chant 16 rounds, and keep yourself engaged in the service of the Lord. Also keep me informed occasionally about your activities.
