The best way to begin the day is to start it early by doing Bhuta Shuddhi or cleansing of the elements. Follow it up by Hatha Yoga to get the best start to the day.
As you do each activity, be mindful at the present moment. That is also yoga. Utter prayers after waking up, while taking bath, before meals and before sleeping. You can chant japa whenever you have some free time.
In the evening, you can Yoga Kriya and then eat food. Most important thing to remember is you should keep a 4 hour gap between eating meals and doing Hatha Yoga or Kriya yoga. But there is no restriction to mindfulness. We can be mindful and choicelessly aware at any given point of time.
Yoga is life. Of course, going to temple, singing devotional songs, chanting slokas and mantras are part of the bhakti yoga tradition. Another great and powerful meditation is “Who am I ?” meditation. Keep doing your best. And remember willpower is everything. Never give up!
