Answer: I am happy to know your interest in the Vedanta. I wish you read the four Yogas by Swami Vivekananda, which will give you a clear idea. It is too difficult to explain in such a small letter. However, first of all you have to get the concept of the word ‘Love’ used in these four Yogas.
In the Bhakti Yoga, it is easy to understand the concept of love. It is pure love towards God, without any expectation. To give a small example, it is just as the mother’s love towards the new born baby. We can say it is love for love’s sake. If such a love can be developed towards God, it definitely brings infinite grace on you.
In Karma Yoga, it is performing all our actions with the spirit of dedicating the fruits of action to the Lord. Or, it is our love towards Him that makes us work for the well being of all.
In Jnana Yoga, it is the idea that the whole world is nothing but the manifestation of God. So, to love all the beings is loving God. In this case, not much of differentiation is made between God and His beings.
In the Raja Yoga, it is almost like Bhakti Yoga. There the love is towards the personal God. Or, it may also mean to feel the divine in our heart by raising the power of Kundalini. When one gets the vision of the Divine, then his heart will be filled with love & bliss.

Response to the above Answer: I have received your reply. I am deeply grateful to you for your kindness. And I have another question. I will be very glad if you answer it.
I am deeply impressed with the idea of strength Swami Vivekananda often emphasizes. What is the meaning of strength in Advaita Vedanta and what should I do in my everyday life in order to be strong?

Reply to the above Response: There are three types of strength mentioned in our scriptures – for the holistic development of a person. All these three types of strength are necessary.
These are – 1. Physical Strength, 2. Mental Strength,
3. Spiritual Strength.
They are called in Sanskrit as –
1. Baahu Balam,
2. Mano Balam,
3. Aatma Balam, respectively.
Swamiji (Swami Vivekananda) always meant these three things wherever he refers to fearlessness. But, to acquire this, we have to be very pure & truthful. The fear comes because we don’t hold to truth strictly.
Gandhiji is a great example for his fearlessness because, he valued truth at most.

RESPONSE to the Above REPLY : I am grateful to you for your answer from the bottom of my heart. Although spiritual ideal in vedanta seems to be very high to me, I am going to put the great priciples of vedanta,especially what Swami Vivekananda exhorts into practice in my daily life as possible as I can. I am always looking forward to seeing your wonderful and helpful website.
