te they (divine perceptions)
samadhau in samadhi
upasargah hindrances, obstacles
hane rising up, following one's own inclination, outgoing mind siddhayah powers
These attainments are impediments to samadhi, although they are powers in active life.
Divine perceptions are hindrances to a yogi, whose wisdom is supreme and whose goal is spiritual absorption. They are great accomplishments, but he should know that they fall within the range of the gunas of nature, and in acquiring them, he might forget his main aim in life and luxuriate within them. If they are shunned, however, they become aids to samadhi.
The yogi may mistake these accomplishments and rewards for the end and aim of yogic practices. He might imagine that he has attained great spiritual heights, and that whatever is attainable through yoga has been achieved. In this process, he can forget the goal of Self-Realisation.
Patanjali warns yogis to treat these powers as impediments in their sadhana. One should control them as whole-heartedly as one fought earlier to conquer the afflictions of the body and fluctuations of the mind. Then one can move forward towards kaivalya, emancipation.
