There are no impediments to meditation. The very thought of such obstacles is the greatest impediment.

Pleasure and pain are only aspects of the mind. Our essential nature is happiness

If there is anything besides the Self there is reason to fear? Who sees the second? First, the ego arises and sees objects as external. If the ego does not rise, the Self alone exists and there is no second.

Food affects the mind. For the practice of any kind of yoga, vegetarianism is absolutely necessary since it makes the mind more pure and harmonious.

Keep the remembrance of your real nature alive, even while working, and avoid haste which causes you to forget. Be deliberate. Practice meditation to still the mind and cause it to become aware of its true relationship to the Self which supports it. Do not imagine that it is you who are doing the work. Think that is the underlying current which is doing it. Identify yourself with the current.

What comes will also go. What always is will alone remain.

Meditation depends upon the strength of mind. It must be unceasing even when one is engaged in work. Particular time for it is meant for novices.
