5. The end result of both the Path of Action as well as the Path of Knowledge is the same – God Realisation. The only difference is that yogis, active ones, are at the starting point of the path while the sankhyas, contemplative ones, are towards the end of the journey.
Yah pasyati sah pasyati – One who sees, sees. One who sees the totality – how we emerged from Brahman, where we are, what is happening in the world, where we are heading etc. sees. When you see the entirety there is total objectivity, no involvement. Such a person understands that vasanas, nature, will function helplessly. There is nothing you can do about it. So it does not make sense to get upset. Just understand. Accept. Enjoy. Do not condemn.
You understand a bhogi will indulge in the world and suffer. You see a yogi acting selflessly for self purification, a sannyasi contemplating upon Brahman and a jnani revelling at all times. You neither denounce the bhogi nor get excited about the sannyasi. You merely empathize.
The practical approach is to practise both as per your capacity. Keep acting till you reach a high state of development. Then action will cease by itself. You do not give it up.
6. The starting point is yoga, Path of Action. You cannot directly practice sannyasa. The sage established in yoga soon gets to Brahman.
When you are well established in Karma Yoga, Path of Action, you automatically become a sannyasi. Then, before long you reach Brahman. How long one takes depends on how many vasanas you have and how much effort you put in.
Once you are moving in the right direction it is a matter of time. The important thing is to change course from outward to inward seeking. And strengthen the desire for Enlightenment. Everything else falls in place. Sri Ramakrishna says you should want God with the same fervour as a man whose head is under water yearns for oxygen!
