Mindfulness is not something we can practice "sometimes"...it is something we should incorporate into every aspect of our lives.
I went for a float tank session this week and had an amazing spiritual experience. I have these experiences whenever I remove myself from the existence that is busy day to day living, set an intention and then be 100% open to and accepting of what comes during meditation (which for me is either reiki, yoga, pilates, painting, sound therapy or floating which is sensory deprivation)
After this particular float session, I thought to myself "wow I need to set time aside to have an experience like this every few months... My next thought was - every few months?! This means in 90 days, I would be meditating/setting aside time to tune out once - 1 out of 90 days... When I look at it like this, meditating 1 out of 90 days is closer to not meditating at all, than making it a practice! Don't get me wrong, it's better than nothing, but it is not going to get me closer to where I want to be.
Mindfulness is something that has to be practiced daily, in every aspect of our life. It begins with being 100% conscious of everything we do. From feeling the water as we wash our hands rather than think about what we are doing next, to giving 100% of our attention to the person we are speaking to, listening - without thinking about our response, to thinking about what we are putting into our bodies - and why... It sounds like hard work, and it is, but it means taking responsibility for our own path, which means taking steps towards our goals, and our wellness to ensure we can be the best version of ourselves in this existence.
The difference between humans, and animals is that we have the freedom to choose. It would be silly to not to.
