Cheating and weakness are two seperate things. Persons devoid of a cheating propensity achieve perfection in life, but a cheater is never successful. Vaisnavism is another name for simplicity. Cheaters are nondevotees. Sincere persons can be weak, but they are not cheaters. Cheaters say something but do something else. Weak people are embarrassed by their defects, whereas cheaters are maddened by their achievements. “I will cheat the acharya,” “I will deceive the doctor,” “I will nourish the poisonous snake of my sinful propensity with banana and milk, hiding him in the hole of my cheating propensity,” and “I will demand name and fame from the people while posing as a saint”: these are not symptoms of weakness but of utter deceitfulness. Such cheaters will never achieve any good. By hearing humbly from saints with a sincere attitude, however, one will gradually attain auspiciousness. After accepting tridandi-sannyasa if one remains busy with worldly activities, thinking that family life is more important than spiritual life or maintaining the sinful mentality of kidnapping Sita from Rama as Ravana did even while dressed as a devotee, then one is a self-killer. We are far from the worship of Hari. Even if we have weakness and have enough anarthas to last us for millions of years, we are not as misfortunate as if we posessed a cheating propensity. It is better to take birth as animals or birds than to take shelter of cheating. (from Amrita Vani by BhaktisiddhantaSarasvati)
Fine Sources for Mridanga & Culture

(Learn with these sources at your own discrimination. This literature does not present my personal opinions.)

^ This is Vaisnava literature d=79356&RQT=309&VName=PQD

^ This is a Master’s dissertation on the mridanga at an american university. The mridanga drum is also known as a khol and so the title is
“ Rhythmic Theology: Khol Drumming in Chaitanya Vaishnava Kirtan ”
This is an excellent study of the complexity, depth, and multi-dynamic nature behind the khol drum, it’s rhythm and it’s culture. It’s an academic paper, so if you find those a bore, I still recommend reading it to understand a glimpse of thick moral behind the mridanga, Shri Mridanga. (However, you’ll need an institution to authorize a copy online. If you can’t access it, let me know and I’ll gladly forward the literature)
^ Guadiya Vaishnava songbook.
(This reminds me of books & prints of Son Jarocho verses and sones. This website compiles prayers, oraciones, mantras, etiquette, songs, bhajans, & information on Vaishnava practice)
