These two Shlokas describe the practical method to practice Dhyan Yoga(Meditation). For the effective practice of Dhyan Yoga. following methods should be followed:

1. Body Posture:
While sitting in the position of meditation, the body should be straight(erect) and in the same line with neck and head. There should not be any movement in the body, neck or eyes.

2. Focusing eyes:
The focus should be on the tip of the nose. This is interesting to note here that Shlokas states not to look around, and then in next words, they say the focus should be on the tip of the nose, means Shloka describe the process just before the start of the meditation because for meditation one has to close his eyes and concentrate on Agya Chakra(between two eyes, Ch5.Sh#28). To start the meditation one should first learn to fix his eyes and for that, he should start with looking at the tip of the nose.

3. Celibacy(Brahmacharya):
Brahmacharya is the term used to renounce all sexual desires, lust and physical luxury. Brahmacharya is also signified self-control and discipline. To attain expertise in yoga one should renounce physical attractions and follow a strict discipline.

3. The devotion:
One of the most factors to attain expertise in yoga is devotion. The highest state of yoga is nothing but the realization of Brahman the eternal universe life energy emanating from Bhagvan Shri Krishna. He is the ultimate power behind all yogic powers. Hence one who wants to achieve the highest state of yoga must have devotion to Shri Krishna. Even little devotion work as wonders for those who are looking for serious meditation.
