Yoga Field

The Yogas appear different only as a starting point. When the end result is reached – Raja yoga is the same as Karm Yoga, Jnan or Gyana Yoga and Bhakti yoga.
Let me explain. One must have the concrete experience and one must know and experience who or what the soul is. That soul is you. When that is experienced (not just an intellectual or faith based feeling), one can say that he has the knowledge or Gyana. So in this sense you can call it Gyana yoga. To experience this, one must get rid of all the coverings of so called book knowledge, passions, desires). This soul, by itself has only one desire and that is to be and please God. So, if there is anyother desire besides that of wanting God, know that you are not established in the soul. So in this regard, one can say that this stage it is Bhakti Yoga because there is only one burning desire of the soul – to serve God. At this point, the soul stops listening to the external clammor of the desires or ego based false knowledge and listens only to the divine guidance and acts accordingly. This is then known as karma yoga.
This is hard to explain in words, since it is a matter of experience.
I merely quote from the words of Great Saints. Forgive me for any mistakes that may have occured in the translation.
This is why you will never see great saints debate or argue. At a higher stage, all branches appear the same. The differences exist only in the gross physical world and in the method of starting.

PURPORT
The culmination of all kinds of yoga practices lies in bhakti yoga. All other yogas are but means to come to the point of bhakti in bhakti-yoga. Yoga actually means bhakti-yoga; all other yogas are progressions toward the destination of bhakti-yoga. From the beginning of karma-yoga to the end of bhakti-yoga is a long way to self-realization. Karma-yoga, without fruitive results, is the beginning of this path. When karma-yoga increases in knowledge and renunciation, the stage is called jïäna-yoga. When jïäna-yoga increases in meditation on the Supersoul by different physical processes, and the mind is on Him, it is called astanga-yoga. And when one surpasses the astanga-yoga and comes to the point of the Supreme Personality of Godhead Krishna, it is called bhakti yoga, the culmination. Factually, bhakti-yoga is the ultimate goal, but to analyze bhakti-yoga minutely one has to understand these other yogas. The yoga who is progressive is therefore on the true path of eternal good fortune. One who sticks to a particular point and does not make further progress is called by that particular name: karma-yoga, jnäna-yoga or dhyäna-yoga, räja-yoga, hatha-yoga, etc. If one is fortunate enough to come to the point of bhakti-yoga, it is to be understood that he has surpassed all other yogas. Therefore, to become Krishna conscious is the highest stage of yoga, just as, when we speak of Himälayan, we refer to the world’s highest mountains, of which the highest peak, Mount Everest, is considered to be the culmination.
It is by great fortune that one comes to Krishna consciousness on the path of bhakti-yoga to become well situated according to the Vedic direction. The ideal yogé concentrates his attention on Krishna who is called Syämasundara, who is as beautifully colored as a cloud, whose lotuslike face is as effulgent as the sun, whose dress is brilliant with jewels and whose body is flower-garlanded. Illuminating all sides is His gorgeous luster, which is called the brahmajyoti. He incarnates in different forms such as Räma, Nåsimha, Varäha and Krishna, the Supreme Personality of Godhead, and He descends like a human being, as the son of mother Yaçodä, and He is known as Krishna, Govinda and Väsudeva. He is the perfect child, husband, friend and master, and He is full with all opulences and transcendental qualities. If one remains fully conscious of these features of the Lord, he is called the highest yogi.
This stage of highest perfection in yoga can be attained only by bhakti-yoga, as is confirmed in all Vedic literature:
yasya deve parä bhaktir
yathä deve tathä gurau
tasyaite kathitä hy arthäh
prakäsante mahätmanah
“Only unto those great souls who have implicit faith in both the Lord and the spiritual master are all the imports of Vedic knowledge automatically revealed.” [SU 6.23]
Bhaktir asya bhajanam tad ihämutropädhi-nairäsyenämuñmin manah-kalpanam, etad eva naiñkarmyam. “Bhakti means devotional service to the Lord which is free from desire for material profit, either in this life or in the next. Devoid of such inclinations, one should fully absorb the mind in the Supreme. That is the purpose of naiñkarmya.” (Gopäla-täpané Upanisad 1.15)
These are some of the means for performance of bhakti, or Krishna consciousness, the highest perfectional stage of the yoga system.

answer from hladini shakthi is right.

other kinds of yoga has been rejected out by both Krishna and Arjuna themselves in the Bhagavad Gita if one reads Bhagavad Gita from the beginning to the end. Neither all other yoga systems are impractical for the age of kali [ kaliyuga] nor they are pure in nature. Only unalloyed devotion to the Supreme Personality of Godhead can please him. Not any gymanstics or mental speculation. Only love which is pure can please him and he has always proved. No greatest yogi, Karmi, jnani has moved him. He is always conquered by his pure devotees starting from Srimati Radharani, the gopis, yashoda and nanda maharaji etc…,.

In the Padma Purana it is said:

naham tisthami vaikunthe
yoginam hrdayesu va
tatra tisthami Narada
yatra gayanti mad-bhaktah

Krsna once told Narada, “I never live in Vaikuntha, nor do I live in the hearts of the yogis. I live in the hearts of pure devotees. I live wherever they remember me, and I take rest very comfortably there. I do not live anywhere else.”

You should chant ‘yoga, yoga , yoga’ three times in a day in dark. Then switch on the lights. You will get enlightened.
