Of course.
The basic program takes only 15-30 minutes, and it is still useful, you will have time. If you usually do it at night, you can build an
Aura of Protection based on
Lunar Energies (although
Solar Energy is also important for the Soul). Many Meditations can be done even on the way to and from work if you are not driving.
Such as
Foundation Meditation,
Sound Meditation,
Color Meditation,
Chakra Alignment,
Chakra Spin,
Chakra Breathing,
Void Meditation,
Meditating on Clairvoyance Points,
Ball of Light Meditation can be done freely even in crowded places, since they don't require Mantra vibrations and other attention-grabbing things (
if that's what you're worried about). All you will need for these Meditations is
concentration,
Visualization,
inhaling the Energies,
feeling and Manipulating the Energy. This can be done silently and even with your eyes open, but if you are comfortable, you can do it with your eyes closed (
again, people will think you either didn't get enough sleep in the morning or are tired after work). The above practices in their basic variations do not take much time, so you can also do them at home if you want privacy and comfort.
As for your wife, you can gently initiate her into your
«Spiritual side». Not by laying it all out at once, but by getting her interested. For example, you could do
Breathing exercises (Pranayama) and
Hatha Yoga together. There are usually no questions or misunderstandings about such practices, because they are common knowledge, and you have their Satanic variants, i. e. absolutely working and tested. So both of you will gradually develop. And then shed light on the rest of your Meditations. If she loves you, she will accept it like any sane person would. If you are wary of giving her Knowledge about who Satan is, etc., you can stop here. It will in any case have its effect in the future.
