As it is true that the supreme Lord is only one and absolute, why are there different types of religious followers?

If food is meant only to satisfy hunger, then why do we have so many varieties?
If clothes are meant only to cover our body, then why are there so many models and designs of them?
If houses are meant only for shelter, then why are there so many varieties in them?
It is because human beings like varieties to suit their tastes. In the same way, to reach the one supreme Lord, there are different ways and means. One can choose one particular path according to his taste and stick on to it.

If God knows what is bad and what is good, why does he often test his disciples?

As you have said, God knows what is good and what is bad. He wants to confirm with his disciples if they have understood what is good and what is bad. That is why He tests them.

Why does God need to be praised with Nama Kirtan being done non-stop? It is similar to politicians’ request during election, is it not? Why do people have to contribute in Hundis or to the priest when it is God’s responsibility to protect the man serving Him?

God is ‘Stuti Priyan’. If you chant the Names of God, He bestows benediction to you. Some chant the Names in gratitude to the Lord, for they look at themselves and feel grateful for what is endowed to them by Him. These people are higher class of devotees. God’s responsibility to humans are like a father’s responsibilities to ensure child grows properly. No father would like to spoon-feed the child all his life, and in doing so would spoil the chances of his child standing in his own legs.
God has many ways of protecting his devotees, he also gives you and me a chance to participate in his endeavor! Why should god preclude humans in doing his job?

We usually remember God when we go through tough times in our lives. Isn’t this like ‘latching’ on to God to escape the reality of the situation? Were God and His forms created (or invented) to help people in distressed situations? Is there really a Krishna or a Vishnu? If so, how are they different from the ultimate truth?

God is ‘what is’. We can’t ‘latch’ on to God to escape ‘what is’! God and his forms were certainly not created for convenience! Whatever is real is Krishna! Are you for real? The real ‘reality’ in you is Krishna. Like light is both a particle and a wave and exhibits its property depending on the context! Krishna is with a beautiful form and beyond form in the same token. This is not what intellect is trained to see. So it refuses to accept. Krishna is indeed beyond our little intellect. Krishna can be realized only by pure love. That love, can sprout only by his grace. His grace descends when we chant the Mahamantra. Mechanical chanting is the only starting point we can attempt. It matures to love by grace.

What is God? Where is He?

Pure bliss and consciousness is God. He is omnipresent, omnipotent and omniscient.

Do all the names Ganesha, Muruga, Shiva, Vishnu, Ayyapa, point to the same God? Or is it true that Krishna is the Supreme God and others are Demigods or devotees of Krishna?

In our Sanathana Dharma, there are many schools of thought. According to one of them, Vishnu is the supreme. Another claims that Shiva is the Supreme. Similarly, there are schools that claim supremacy of Devi, Surya, Ganapathy and Muruga. One cannot be compelled or convinced to sign into one school of thought. It is upto his own taste and interest, and above all his luck.

What is the best boon to ask for from God? Is it good to pray to Him with the thought “Oh Lord! Give me what ever you wish for”?

If God appears before you, do not ask him for wealth, remedy for suffering, power, fame or anything worldly. Also, do not ask him for the attainment of the purpose of life as per Advaita, Vishishtadvaita , Dvaita or such high philosophies. Just ask him one simple thing. Ask him to give Himself to you. That is the best prayer to ask God.

Is God personal or Impersonal? If impersonal what is the necessity of idol worship?

The Lord is omnipresent and all-pervading. He is full of consciousness and knowledge. It is not possible for a ‘jeeva’ to visualize such a ‘God’. So it is easy and convenient for him to worship God in the form of an idol.
The omnipresent, omnipotent and omniscient Lord understands his worship and out of sheer mercy makes the ‘jeeva’ realize Him through the idol.

Our religion says that the supreme God is one and is beyond name and form. Why then does our scriptures talk about so many Devas, Demigods and the like? Some even make fun of this. How come there are so many Gods as per our tradition?

Yes there is no second opinion about the fact that the Supreme is the Brahman which is beyond name and form. But as long as we live and perceive that the physical body and the external world to be real, we take help from so many things in this world.
The tree gives us shelter and fruits. The dog guards the house. The horses and bulls work for us. The cow gives us milk. The bees collect honey which we use. The crops give us grains. We derive various favours from all these beings. Some beings like snakes and scorpions harm us. The same way the Devas and the like are higher beings by pleasing whom we could have our wishes granted. Some may grant us children. Some may bless us with wealth. There are some evil beings that may harm us. Owing to their superior powers and ability to fulfill wishes these higher beings are referred to as Devas and sometimes offered the status of God as is common practice amongst people to call any great soul, rishi or sage as God himself.
But the fact is, the end point of religion is the one Supreme God alone.

Good morning! I am ten years old. My mom says god created us. I want to know who created GOD.

Dear child, If I tell you who created God, you will then ask me who created Him. So the answer is ‘you’.
