You may be a little tired, but a shower will perk you right up. Meditate each day at noon, just for a few minutes. The kundalini is strongest at noon. Meditate at sunset or at night. It's easiest to meditate at night.
Night is eternal.
It is good to meditate at any time. You will find that some times are better than others. Do what works for you. Be creative in your meditation. Once a day, it's fun to meditate outside.
