Questions on behaviour

Hi Sir,

I hope you are well. I have three questions that require your advice.

1.) When walking in the street, Swami Sivananda recommends keeping the eyes down. However, this prevents one from enjoying vocations (such as sightseeing), and makes social interactions awkward. I also look like a person who's feigning humility. Should I rather keep my eyes up and behave like a normal person?

2.) However, there is the issue of the lustful look. My question is: When will this go away and fully disappear? If my eyes are up, I have to actively restrain them.

3.) Also, the images of some damsels who appear exceedingly beautiful still haunt my head. I assume the best way to get rid of these images is to remember the divine, and remind myself I am "pure consciousness"?  

4.) Finally, there is the issue of men staring at me and trying to intimidate me because there are jealous or hate me. What is the best way to react in this case? You have said one must get rid of the ego in this situation. What would you recommend as the optimal reaction? Should one stare back at them? Should one ignore them?

5.) When I am in the company of a woman on the subway, typically I stare at the ground, at the woman's feet, and say "Om, Sri Durga Devyai Namaha" in my head. I assume this is the best way to react?
