There never was an easiest way to follow lessons of Bhagavad Gita. The teachings contained in Bhagavad Gita were foremost of all scriptural writings available in world today. If one can reach state of enlightenment in present life time, it is only through teachings of Bhagavad Gita.
Everything contained in Bhagavad Gita can be understood only by indulgence in contemplation (chintan) something people world over avoided. We have to master delicate art of contemplation (chintan) to successfully indulge in spirituality contained in Bhagavad Gita. There never was a shortcut method on path of pure spirituality other than indulgence in chintan (contemplation).
How many people do we think succeed reaching state of enlightenment in a timeframe of 100 to 200 years world over! As ordained by God it can be a maximum of two persons. Understanding spirituality contained in Bhagavad Gita and reaching state of enlightenment is not easy. Indulgence in contemplation (chintan) needs time.
I started in pursuit of God six years of age. Still I took more than seven years of contemplation before I realized the difference between Dharma, religion and spirituality. In my 55 years of spiritual travail I have yet to find a person who can detail to me the correct meaning and definition of Dharma, religion and spirituality.
Ritually or through mere book reading nothing on path of spirituality becomes clear. We have to all the time follow path of jnana yoga (absolute wisdom) to reach the hidden underlying meanings of sacred texts. Nothing in Bhagavad Gita becomes clear indulging in bhakti yoga or karma yoga alone. In present Kali Yuga (Dark Age) path of jnana yoga is the only means to cut across darkness of ignorance.
As a human being, the highest manifest stage in cosmic life cycle we should realize that we had only one lifespan, the present earthly domain. Whatever we want to do or accomplish, we had to do it in present life time. As the journey of life belonged to spirit existing in our heart as soul atman, we must follow dictates of soul atman coming from within our heart. Lord Krishna from within our heart all the time tells us to indulge in spirituality to reach cosmic end of life. But guided by a bloated ego, we always suppressed voice of Lord Krishna coming from within.
Allegorically Lord Krishna existing in our heart is the spirit, soul atman that manifested human form.
Unmindful of the fact, how much time spiritual journey takes, we must indulge in spirituality full force. Only then we can hope to achieve something worthwhile spiritually in present life time.
