(1) concentration and (2) casting off distractions?
M.:
Physically the digestive and other organs are kept free from irritation. Therefore food is regulated both in quantity and quality. Non-irritants are eaten, avoiding chillies, excess of salt, onions, wine, opium, etc. Avoid constipation, drowsiness and excitement, and all foods which induce them. Mentally take interest in one thing and fix the mind on it. Let such interest be all-absorbing to the exclusion of everything else. This is dispassion (vairagya) and concentration. God or mantra may be chosen. The mind gains strength to grasp the subtle and merge into it.
