О запрете умозрительного философствования

Вот примеры писем Шрилы Прабхупады, где он трактует один из регулирующих принципов как "не играть в азартные игры и не заниматься умозрительным философствованием":

He is advised to strictly follow the regulative principles of 1. no eating of meat, fish, or eggs; 2. no taking of intoxicants including coffee, tea, and tobacco; 3. no illicit sex-life; and 4. no gambling or mental speculation.
