Celibacy/Abstinence/Women's habits are the main causes of failure
I know you said that no force outside is the cause of one failing. In the society more and more says men are the one that are immoral. But in reality and practice women's habits and television are the main causes of failing in most men, this is the truth. Do you really think it takes the same efforts to practice brahmacharya in a conservative society where women dress modestly and in another society where they dress in a libertarian way? Do you live in Usa? It is easy to point which societies, places and countries are moral and which of them are not.
1. Two children are born in the same house, grow in the same environment, yet have different destinies. One becomes a good citizen, while the other becomes a criminal. Why the difference?
2. That which is experienced externally, is but a reflection of what is inside. The world is a reflection of one's own nature. Based on the nature of karma accrued by an individual, a corresponding external set of experiences accrue, termed as the world. Te same world manifests differently, for different individuals, based on the nature of past karma.
3. Each Jiva finds itself in the set of circumstances, as earned by it through past karma. These are then represented in the form of lifestyle, society, friends & environment.
The mind (fueled by past karma) goes in search of what it wants, immaterial of whether it is in a conservative environment or libertarian. It is not that conservative societies are favorable for the practice, nor that practice is not possible elsewhere. Those who are intent on the goal are not affected by it; while those less committed, find Sadhana difficult, even in favorable circumstances. It is not woman but man's ignorance, which is the cause for his downfall.
