all the books you have read are at the same level of Srimad Bhagavatam, they're not less saint or esoteric

so if you increase in quality and quantity your japa rounds and if you became completely vegetarian it is surely necessary to progress in spiritual life, but you also can read srimad bhagavatam from now on

i repeat it : "Krsna, Bhagavad Gita, Krsna-Reservoir of Pleasure, Facts for Life, Science of Self Realization" are not less sacred than Srimad Bhagavatam.. so if you are reading these books simply go on and read also bhagavatam.. where's the problem?
