Living in a monastery were always strange to the ancient Sanatana Dharma. Monastery system in the Hinduism is the influence of Buddhism and Jainism.

Self-knowledge or Brahma Gnana or Atma Gnana arises when one indulges in deeper discrimination between the real and unreal.

Self-knowledge or Brahma Gnana or Atma Gnana annihilates all ignorance. Without the Self -knowledge or Brahma Gnana or Atma Gnana Advaitic Self-awareness is impossible.

Religion unanimously holds the chief means of attaining Self -knowledge or Brahma Gnana or Atma Gnana is sannyasa, which means the renunciation of all action and worldly desires, to be an essential element of spiritual contemplation.

Nevertheless, indifference to practical life within the practical world, control of senses, eagerness to attain salvation, places, and time without distraction, and other factors are necessary, in the path of orthodoxy. But in the path of wisdom or reason, the sannyasa or monkhood is a great obstacle because the sannyasa and the world are merely an illusion from the standpoint of the Soul, the Self.

People who believe the sannyasa or monkhood is the means to acquire Self -knowledge or Brahma Gnana or Atma Gnana are taken the wrong path.

The orthodox view is based on the false self (ego) within the false experience (waking) because the orthodoxy holds the experience of birth, life, death, and the world (waking) as reality. Those who attained monastic knowledge are unfit to acquire Self -knowledge or Brahma Gnana or Atma Gnana.

The Monastic path is the path of ignorance because it based on the false Self within the illusory universe or Maya.

Remember:~

Celibacy and living in a monastery were always strange to the ancient Sanatana Dharma. In fact, almost all the great Sages of the Vedic era were householders. 

Observing celibacy and the monastery system in the Hindusim is the influence of Buddhism and Jainism. Hinduism is a mixture of   Jainism, and Buddhism, and many other ideologies. Hindusim is not ancient Sanatana Dharma. 

There is no need to renounce anything, other than ignorance. Renouncing worldly life and becoming a sanyasi is not needed for Self-realization.  Sanyasa is not the means to Self-Realization. Sanyasa is nothing to do with the ultimate truth or Brahman or God in truth.  

Whatever renounced on the base of the ego or physical self cannot be the qualification to acquire Self-knowledge.  

There is no use in giving up the worldly life and become a monk or sanyasi, in order to get self-realization, because all the physical activity is part of the illusory universe or Maya. 

Renunciation is a religious idea and it is the greatest obstacle in pursuit of truth. The sanyasi thinks he is an individual separate from the world, therefore; he will not be able to renounce the ignorance. Therefore, he is not qualified for Self-knowledge.

Religionists cannot take a comprehensive view and so decry what they cannot understand. There is no need to get an aversion to the existence, as do the ascetics and yogis; on the contrary,   he should go on living in the world, as a householder and he should accept worldly life like any other commoner.

There is no need to give up anything in order to acquire nondual wisdom, but to know “What is truth “and “What is untruth” in order to assimilate Self-knowledge. 

Religious people think The method of asceticism is where one gives up externally in order to help one get into the internal attitude of freedom from desire but by getting rid of the desire, the ignorance will not vanish. Without getting rid of ignorance the Self-realization is an impossibility. :~Santthosh Kumaar
