I do very well at morning meditation, almost every morning. Evening is very much different. I find it much harder to do consistently. Being a householder with family many times I can talk myself out of it — 'I’m just too tired.'
Does anyone else have this difficulty?
Your struggle with the evening meditation is not uncommon after a long and intensely active day!
Having a solid and dependable morning meditation can be your "sadhana anchor" (how your meditation is firmly established).
At night, then, until perhaps some time when this can improve, can be the "lesser" meditation.
It can be a time to step away from the busy-ness of the day and rest in God, even if for a few minutes or a much shorter time than in the morning.
Say to yourself "I will never go to bed without a few minutes alone with God: in gratitude for the day, my life, in prayer for strength, wisdom, and love for God in all."
So by allowing yourself to have a lesser meditation you may find that the tension is released and you can find yourself not resisting it so much.
Be sure to use at least a few of the tensing yoga exercises (Energization Exercises) before sitting for the evening meditation.
This will help throw off fatigue and the day’s burden for at least long enough to be still and devotionally present.
