Q: What makes good conditions for sadhana?
Aspiration, untiring will, steady calm and detachment, make the best conditions.
Q: Today I could control for a while the lower forces that were bothering me, but later on they prevailed over me.
It is the nature of the sadhana. The forces of the Ignorance are a perversion of the earth-nature and the adverse Powers make use of them. They do not give up their control of men without a struggle. The one thing wrong would be to allow yourself to be overcome by them. If you remain steady in yourself, you can repel the attack or else it will exhaust itself and pass. In such circumstances you have to be like a cliff attacked by a stormy sea but never submerged by it.
