How to practice
Fluctuation, in the long run, does not give the results that daily meditation of even five minutes produces. If you have to dig for oil or water and you dig a few feet some days and skip totally for months and then start again, the goal that you want to achieve will be delayed an indefinite period of time. Even if you dig a couple of inches a day but do it in a regular fashion, you will achieve your goal much faster.
Regular practice creates a regular, balanced mind. That’s why the yogis say to avoid changing the time, place, and posture for meditation. It is most beneficial to use the same asan (cloth or cushion) and use the same technique. If you are using a mantra, stick with the same mantra each day. Whatever form of the divine you relate to, keep that constant. One path. One teacher. These are the basic guidelines and the keys to success.
When you do this continuously, the mind, regardless of how strong and stubborn it may be, will be brought under control. That control will manifest not only in spiritual practices but also extend to your daily life.
When your mantra is repeated in a stable way on an asan (seat) on solid ground, the complete benefit, the complete energy, is attained. It is also beneficial to repeat a mantra when you are moving from place to place so that the mind constantly remembers the Divine, but technically, in terms of daily practices, a seated practice in the same place daily is what brings the greatest benefits.
