I can only answer from my own viewpoint.
Generally speaking it does not bother me how or in which form someone directs their mind towards God.
Because for me, God is the Higher Self in everything, the Cosmic Consciousness where everything and everyone originated and will one day return.
But I do have a certain idea about God or gods (not originally my own idea) which helps me to make distinctions for myself only.
I distinguish four or five categories:
1. Brahman, the Cosmic Consciousness behind or within everything and beyond place and time.
This is in my eyes the exact same as Allah or the Christian God or Beloved Father (Jahweh).
2. Taraka Brahma, mysterious Guru's, historical personalities born with all of the occult powers who are born fully spiritually realized and who change the destiny of humanity by the impact of their lives in response to great need in human society in the time period before they are born.
3. more minor guru's who become deified, turned into gods, e.g. Jesus.
4. invented gods (by humans) who symbolize certain qualities that they wish to emulate by honouring and worshipping them.
5. invented gods that symbolize the forces of nature that humans fear and wish to appease.
The fifth category should be the oldest in the history of humankind, although the first one was always there without us noticing it.
A quote from a short talk given by P.R. Sarkar in 1969 in Ranchi, Bihar which says something more about
Taraka Brahma:
WHEN DOES HE APPEAR?
______________________________________________
He comes on earth when there is too much sin and it is difficult for virtuous people to live on earth. When dharma declines and
adharma , or sin, gets the upperhand; when the virtuous and the pious are tortured and the dishonest and evil-doers tyrannize over the good; in a word, when the human intellect is guided along degraded and destructive channels,
Taraka Brahma forms a desire to come on earth with a specific mission of restoring dharma by launching a ceaseless fight against all injustice and sin.
There are a few notable criteria by which to distinguish
Taraka Brahma from other
Mahápurushas:
1. He Himself is a born guru and has no spiritual guru.
2. He comes with a specific mission, which is to restore morality and dharma. The entire society becomes divided between moralists and immoralists. A fight between them is inevitable, and ultimately dharma comes out victorious.
3. His emergence means a new era of white peace and dharma.
He needs no
sádhaná, but just to set an example to others, He performs
sádhaná with the masses.
Shri Shri Anandamurti 1969, Ranchi (quoted from Discourses on Tantra Volume 2, page 92)
That could be the reason you sometimes see Lord Shiva pictured as sitting in a meditation pose.
He doesn't need to do sadhana for Himself but He does it to set an example.
I've never seen Lord Krishna pictured in a meditation pose though.
