O best of Bharata (Arjuna), the predominance of Rajas gives rise to tendencies of greed, activity, restlessness, craving and undertaking selfish actions. 12
When there is an increase in Rajoguṇa, then tendencies of greed, activity etc increase. Therefore at these times, aspirant should think that when nothing at all belongs to him in all the universes, all objects come and go, what does he need for himself? By thinking like this he should abandon all Rajasic tendencies and should become indifferent from them.
'Rajoguṇa' is contrary to detachment — 'rajo rāgātmakaṁ viddhi' (14/7). A man attains Yoga only when he is detached from actions and objects (Gītā 6/4). But due to attachment to actions and objects the Rajoguṇa does not let a man attain to Yoga.
