Modes of Material Nature: Mode of Passion

                                                                  Q. In Bhagavad-gita (17.9) Krishna states that 'Foods that are too bitter, too sour, salty, hot, pungent, dry and burning are dear to those in the mode of passion. Such foods cause distress, misery and disease.'

                                                                  * When I go to the Sunday Feast at the temple, sometimes the food is very hot. Should I quote this verse of the Gita to the cook? Or are hot spices, like chili, an exception?

                                                                  Q. If someone say's even Hitler was vegetarian but he created so much havoc. How can one support the argument that vegetarian food results in pleasant thoughts.

                                                                  Q. I would appreciate if you can elaborate on why we should not consume or eat either onion or garlic. Is it stated in any Sastra? Please help me this question will be helpful for my preaching purpose.

                                                                  Q.  Renunciation of prescribed duty is condemned in the Bhagavad-gita As It Is verse 18.7, 18.8. Also in the purport to verse 3.4 Srila Prabhupada disapproves premature renunciation, but then he gives the bottomline, "On the other hand, if someone takes to the transcendental service of the Lord, even without discharging his prescribed duties, whatever he is able to advance in the cause is accepted by the Lord."
                                                                  So, isn't Prabhupada giving a license here especially for students who want to practice bhakti as an escape-way to studies? Please explain the matter briefly and remove my misconceptions. I beg for your help.
