Limitations in Yogic practice due to work conditions

QUESTION: Hello
I have a few follow up questions wrt to some of your past answers:
1) If one is not able to maintain a pure lifestyle and absolute purity of food(eg: eating out, meeting different kinds of people), due to his nature of job or business travel,etc, then is it recommended to continue what ever little sadhana that he has been doing? and don't give such an importance to the practice of brahmacharya till the time he arranges/attains the above conditions? What do you suggest some one who is caught up in such a prarabdha in his current life stage?
2# In your earlier answers, you said there can be an involuntary transfer of prana/karma from the person who cooks the food.. I am just wondering what will be the state of food that is machine generated as is the case with lot of food items now a days#automatic, un touched by human kind of processing), etc?

ANSWER: 1. One should follow the tenets of Yoga & Brahmacharya to the best possible extent. When cent percent practice of the rules is not possible due to unavoidable worldly situations/work conditions, one should practice with devotion to whatever extent possible within one’s reach. In the Bhagavad-Gita, Lord Krishna describes this with the statement – “Swalpamapyasya dharmasya traayate mahato bhayaat” – “O Arjuna, even a little bit of this dharma (Yoga) will help man tide over great suffering”.

Due to one’s ‘Prârabdha’ (past karma bearing fruit now), one sometimes may be placed in unfavourable conditions against Yoga & Brahmacharya. This is only a divine test to check the honesty of the devotee. Under such conditions, one should always continue to think of God, surrender all actions to HIM with love and devotion and persist with honesty to the best extent possible as regards Yoga & Brahmacharya. Karma then slowly starts dissolving and better conditions blossom in course of time without doubt.

We are afterall the instruments through whom HE works HIS Leela (divine play). If a man is a fisherman who has to spend his whole day at sea, that is also God’s Leela. That great being (Almighty) is working through each and every embodied soul. He who forgets the Lord and performs actions for himself misses out on Yoga, while he who performs all actions rightly and  surrenders all actions as a service to HIM with love gains freedom, and is eventually released from rebirth.

2. A machine only processes the food in part. Who handled the preparatory process of readying the raw materials that went into the food machine? Who is operating the machine? Who is handling the processed food for packing/serving etc..? The Prana-s (and thereby vibrations) from all such sources act on food.

ॐ तत् सत्
(That Supreme being is the absolute truth)

QUESTION: Thanks for the replies!
Regarding answer to question 2, lot more doubts spring in my mind.....
1)Is there any way we can remove the negative vibration from food if we don't know the source? and make it positive and fit for consumption....
2)How do we know if the impurities in us are due to food consumed by us or due to our past negative samskaras?
3)Also does following these type of food restrictions show up as anti-social and narrow behaviour on our part, which is damaging for some one living in a society with all kinds of people...?
3)And is this something to be worried about by only advanced yogis, or is it something which even a beginner has to cultivate right from beginning?

Thanks for your patience
