The current from above and the current from below are familiar features of yogic experience. It is theenergy of the higher Nature and the energy of the lower Nature that become active and turned towards each other and move to meet, one descending, the other ascending. What happens when they meet depends on the sadhak. If his constant will is for the purification of the lower by the higher consciousness, then the meeting results in that and in spiritual progress. If his mind and vital are turbid and clouded, there is a clash, an impure mixture and much disturbance.

That you should be able to keep your consciousness uplifted is already something. As for the opening, its coming and apparent closing is a normal experience it needs several openings before the thing is settled by a permanent poise of the consciousness above and an increasing descent into the head and below. It is the pull from below that should get no indulgence for that though most do indulge in it is a wrong crabby way of doing it. One must be stationed above before one can descend without a tumble. Not that the tumble if it comes precludes a going up again -- it doesn't; but that is no reason for letting it happen.

Her will was puissant on their nature's acts,
Her heart's inexhaustible sweetness lured their hearts,
A being they loved whose bounds exceeded theirs;
Her measure they could not reach but bore her touch,
Answering with the flower's answer to the sun
They gave themselves to her and asked no more.
One greater than themselves, too wide for their ken,
Their minds could not understand nor wholly know,
Their lives replied to hers, moved at her words:
They felt a godhead and obeyed a call,
Answered to her lead and did her work in the world;
Their lives, their natures moved compelled by hers
As if the truth of their own larger selves
Put on an aspect of divinity
To exalt them to a pitch beyond their earth's.
