शनैः शनैरुपरमेद् बुद्ध्या धृतिगृहीतया।
आत्मसंस्थं मनः कृत्वा न किञ्चिदपि चिन्तयेत्।।6.25।।
6.25 One should gradually withdraw with the intellect endowed with steadiness. Making the mind fixed in the Self, one should not think of anything whatsoever.
6.24 - 6.25 There are two kinds of desires: 1) those born of contact between the senses and objects like heat, cold etc.; 2) those generated by our mind (will) like that for sons, land etc. Of these, the latter type of desires are by their own nature relinishable. Relinishing all these by the mind through contemplation on their lack of association with the self; having relinished the ideas of pleasure and pain in respect of unavoidable desires resulting from contract; restraining all the senses on all sides, i.e., from contact with all their objects - one should think of nothing else, i.e., other than the self. Little by little with the help of intellect controlled by firm resolution, i.e., by the power of discrimination, one should think of nothing else, having fixed the mind on the self.
