The ability to let go of undesirable unhappy/painful experiences or to observe unpleasant feelings and thoughts without attachment and identification, or to be undisturbed and undetermined by all the perceptions of names and forms, is nothing to do with whether one practices yoga, or not.
It’s not necessarily that one has to be practicing yoga to be free from ignorance and egoism, and realize unconditional peace and love.
There are people who practice yoga, but they are not peaceful, because they are not free from ignorance and egoism. There are people who don’t practice yoga, but they are peaceful and compassionate, as they are free from ignorance and egoism. And it doesn’t matter whether people think they practice or don’t practice yoga, it’s the same when people realize peace and compassion when the mind is free from ignorance and egoism.
The peacefulness or calmness that derived from the effect of yoga asana, pranayama and concentration practice, is conditional and subject to impermanence.
Meanwhile, the unconditional peace and love is nothing to do with whether one is practicing yoga asana, pranayama and concentration practice, or not. It is always there, never increases nor decreases. It is not a quality that derives from yoga asana, pranayama and concentration practice. It doesn’t belong to those who practice yoga and it exists in all and everyone disregards one practices yoga, or not. Though the yoga practice serves as a tool to purify and quiet the mind to allow the mind to realize this unconditional peace and love that is always there, but not everyone who perform yoga practice can go beyond the mind perception of conditional qualities of names and forms due to deep rooted ignorance and egoism of attachment, identification, craving and aversion.
One can be free and realize unconditional peace and love whether one practices yoga, or not.
There’s nothing to be boast or proud about if one is practicing yoga or one has achieved particular results or benefits from performing the yoga practice. Boasting and pride is part of the characteristics of the ego.
