Karma Yoga or Kriya Yoga (Yoga of Actions) - The Bhagavad Gita Chapter 5 Verse6
संन्यासस्तु महाबाहो दु |
योगयुक्तो मुनिर्ब्रह्म नचिरेणाधिगच्छति || 6||
samnyaas astu mahaa baaho duhkhamaaptum yogatah
yoga jukto munirbrahmam nachirenaa dhi gacchati
(Lord Krishna Teaches)
"But, O’ Arjuna, without the help of Karma (Kriya Yoga) Yoga, it is extremely difficult to give up the idea of the doership (Kartaa Abhiman) of all actions, performed by the body, mind and the senses."
But for those who practice Karma Yoga (Yoga of Actions), thinking of God, most of the time, it becomes much easier to realize God.
